General :: Add 2 Time Fields Together?
Jul 15, 2014
I have an Access 2010 database that tracks Classroom Training. I have a "Start Time" field for each class and a "Duration" field for the length of each class. The Start Time field is a date/time data type and the Duration field is a number data type set to Double with 1 decimal place.
Example:
Start Time = 8:00
Duration = 1.5
So the class should have an End Time at 9:30. I have been able to convert the "Duration" field to a time field for example 1.5 now displays 1:30.
My question is how do I add the 2 fields together to get an End Time of 9:30 ?

I have tried to change the colour of the text in time fields with no a value of 0:00 by using conditional formatting - to no avail.

Currently using Access 2007-2010. I have a text file that I am trying to import into Access. I am having issues with the time fields. I need to be able to sum them in a query or report. When I import it in, Access is put the 12:00:00 am as default and adding numbers to achieve the 11 character field. I need to be able to sum these fields later in the database. The file looks like this:
ACD Calls Avg ACD Time Avg ACW Time ACD Time
Totals 103 3:49 1:07 6:33:45
2 1:25 :00 :02:49
8 2:02 :00 :16:15
2 3:17 3:06 :06:34
17 4:49 6:06 1:21:53

Formatting issue regarding elapsed time calculated using DateDiff().
I understand that you can specify the output value for DateDiff(). In my case I have chosen "n" for minutes. Each result in my query shows the correct calculation in terms of minutes.
[PunchIn] = 11/23/2013 8:11:28 AM
[PunchOut] = 11/23/2013 5:43:30 PM
[ShiftLength] =DateDiff("n", [PunchIn],[PunchOut]) = 572 minutes.
Now when I try to format the result in terms of H:MM (be it in a form or a report) I get varied results. I'll illustrate an example below:
=Format(([ShiftLength]/60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 10.32 Not correct
=Format(([ShiftLength]60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 9.32 This is correct but I need my result to be in the form of a decimal such as my next example
=([ShiftLength]/60) Returns 9.53333333. Getting there but how do I have this result only show two decimal points 9.53?

I have a database with date and time each stored in a separate field. Now I want to query the database based on a start date/time and an end date/time. I started with the code below but it only returns events within the same time range on each day when what I really need is every event from a specified date and time through a specified date and time.
SELECT myTable.ID AS myTable_ID, myDate, myTime, FirstName, LastName
FROM Staff INNER JOIN myTable ON
Staff.ID = myTable.StaffID
WHERE myTable.myDate >= #3/2/2014#
AND myTable.myDate <= #3/3/2014#
AND myTable.myTime >= #8:00PM#
AND myTable.myTime <= #11:00PM#
ORDER BY myDate desc
In the above example what I want is every event from 3/2/2014 8:00PM until 3/3/2014 11:00PM. But what I get instead is every event between 8:00PM and 11:00PM on 3/2/2014 and every event between 8:00PM and 11:00PM on 3/3/2014.

Before I start implementing this, I would like to know if it is possible to do in principle
I want two fields, say TimeStarted and TimeEnded. I then want to subtract the two from one another to see how long the task took.
Is this possible or would i be wasting my time trying it?

Can you calculated time in a query?
Such as hours during any given day?

I have a form generated from infopath where users enter the amount of time it took them to complete a task. It is set up right now in time format, so a user would enter Task A-0:15 (to show 15 minutes). Users have multiple tasks with different times and I would like to be able to show a total for all those tasks combined.
Task A-0:15
Task B-0:45
Task C-1:30
Task D-0:30
Total = 3:00 <------This is what I would like to do

I'm working with a linked table that has a seperate field for the date, and a seperate field for the time (which show in the linked table as '11/30/1899 9:46:00 AM'). I need to calculate the time difference between 2 entries.
How can I merge the 2 fields into a combined date/time field for my calculations?
Thanks,
Sup

i'm relatively advanced Access user but this problem has got me stumped....i've been given a table that's basically a log of operating rooms with fields designating the date, the room number, "patient in room" time and "patient out of room" time. basically, i want to calculate the turnaround time which is the "patient in room" time" minus the "patient out of room" time from the previous record (if records are sorted in sequential order).
any thoughts?

I have a form that asks 2 questions. Date and Account. I need to check a table to see if the combination of both date and account have not been used. Date is normally today, can be yesterday. Account has a drop down menu with 6 choices. If both the date and account have been used then there should be an error shown to that effect. If not used, then proceed on to the next form for data entry.
Can this be done? And how?

I'm creating a form, and all the fields moved together. How do you unlock the field so you can move each one individually. I don't need them in columns as they are, nor the same size.

I am creating a query with criteria for a dates column. The column cotaining dates in my Table has many empty fields. I want to limit the criteria for my dates to >#1/1/2004#, but I don't want Access to exclude all the empty fields because I want all the data displayed for the purposes of my report.
What do I do? I'm not terribly familiar with Access, so please explain as completely as possible. Thanks in advance!

Hi,
I'm combining two date/time fields in a query to an integer. The first field has the date, the second the time. I'd like the resulting integer to be without the opening 0. How can I do that?
That is, these are the two fields:
2006-09-14 (date/time)
15:00:20 (date/time)
And I'd like those two combined to be 60914150020 (integer) in the third field in the query.
Grateful for advice!

I have a database with two fields [RECEIVED] and [DISPATCHED] which unfortunately are text fields which I can't change (linked via ODBC). Time is entered in these fields as military time.
I created a query with [DISPATCHED]-[RECEIVED] which works unless the time spans different hours. Example 1605-1555 returns 50 instead of the correct 10.
Any idea how I can use a query to calculate this accurately. I am an intermediate user. Any help appreciated.

I have a table in which each record includes a field showing the time that an event started and then another field which stores "how long did it take", these two fields are both defined as a short Time. I then have a query that runs through the "how long did it take" fields to produce an average time for the whole sequence of events. Two problems:
1. The average comes out as a decimal like 39553.367942 instead of several hours and minutes.
2. When I try to access this value using DLookup on a form I get "#error"
Any suggestions?
thanks

Hi,
Im having a problem adding the date and time to a new record using a form. The 1st method i used was by inserting the default value set to Date() & Time() functions, this worked fine for over a year, but now on some computers on the network the following error pops up "function is not available in expressions in table-level validation expression".
The 2nd method I tried was to add a macro with 'setvalue' commands to the After Update event of one of the first field's that was entered, this entered the same information into the Time & Date field once the first field was updated. This now brings up the macro fault screen and the 'Halt' button has to be pressed to clear the error.
This only happens on the older computers that access the database, the new computers don't bring up any errors.
Can anyone help me with this problem??!

I created a Contact database where I have the date and time as two separate fields in one of the tables. I have them defined as such, but would prefer that the fields wait until I enter data into them and not auto fill with the current information. Is there a property of these fields I can set so that these fields do not get auto filled? Again this database is too large to send, so I hope that you can help without it.

I have created a table with four fields. The names are:1stBusOn, 1stBusOff, 2ndBusOn, 2ndBusOff.
I want the time for the first two fields and the time for the second two fields to end up in a field called TotalRideTime.
Also, if only one set of the fields are completed I still want that total time to in up in the the TotalRideTime field.

I have been trying for about 8 hours to calculate elapsed time between two fields into a third field in Access 2007. Unfortunately, the expression
IIf(IsNull)([Final Suspense]),DateDiff("d",[Routing Status Date],Date()),DateDiff("d",[Routing Status Date],[Final Suspense]))
is not working. Image enclosed....

For anyone that might be able to help me out, I'd very much appreciate it, as this is now number 2 stupid workaround that I'd like to resolve before I need counselling...;)
I have a Date/Time field that I'm importing into my database via .csv files. The field is setup like the example below in every .csv file:
4/2/2007 8:30:00 AM
Access keeps throwing errors and deleting all the field values in this field whenever I try to import. I know that Access does this when a Date/Time field includes data that is not delimited, but these field values seem to be perfectly formatted to me... what can I do to stop Access from chucking these on import?
Right now I'm just importing the data into a "text" field, and then changing it to "date/time" afterwards, but I'm worried that once the table gets too long I won't be able to re-index all those records anymore and my database will be useless since it depends on that field being "date/time" format...
All those better than I feel free to show me how and where I've been stupid:D

I am trying to display a total based on 3 separate combo boxes in a form. there is a name with an associated number value using 2 fields. the values come from a linked value spreadsheet. the name field is "text" and the number is "number". the user selects their name and number using a combo box drop down window. this occurs 3 times in my form and i want to sum them in a 4th combo box. this is about how it should look, where "Total" happens automatically depending on the name selected.
Lewis 3 Smith 2 Parks 2 Total= 7
thanks for helping.

In my form I have a calculated field that works out the time elapsed for a job, worked out as the QTY/RUN RATE which gives me the time in hours. However I couldn't format the box as a date/time, as it is a calculation and the times may go over 24 Hours which results in the date/time giving me something like 31/12/1899 16:00 for example.
I've got around this now and I've formatted the results as HH:NN:SS using a public function in a module, but the problem is this is now stored as a text field. I've tried setting this to a number field but the formatting doesn't carry over. I've tried setting a custom format in the table as HH:NN:SS but then all I get is just a bunch of 0's, no calculation results.
So how to format this as a number field properly?
Also for any extra information:
- I know you're not supposed to store calculated results, but this is slightly different, the calculated field is a standalone text box and the bound field is a formatted text box.
- The reason I have to store the calculated results is because my boss wants to eventually see a chart of the total hours of jobs each day, hence why I'm asking if this can be done as a number field.

I have a form that contains a subform. On the main form, there are 3 fields: [IncidentNumber], [OpenDate] and [OpenTime]. The subform, [CtrlLog Detail] , contains the log entry details for each incident number. Every incident number can have many log entries. Two of the fields on the subform are [EntryDate] and [EntryTime]. The fields work correctly and the forms are fine.The issue Im having is when a new incident number is created the [OpenDate], [OpenTime] and [EntryDate], [EntryTime] MUST be equal because of some filter queries for statistics. Right now the user must physically type in the date/times in these 4 fields when they create a new incident number, which means I'm having lots of data entry errors.
Using default value on either [EntryDate] or [EntryTime] on the subform doesnt work because it doesnt create a primary key for the underlying table and the subform will not allow any other entry (due to some other linked values) until that PK is created. The forms are based on tables linked by [Activity_ID] as the primary key. I want to create some VBA code to see that if the Incident number is a new number (meaning the user must type in the new incident number creating the primary key for [Activity_ID]), that access will automatically populate the [EntryDate], [EntryTime] fields to match the [OpenDate], [OpenTime] fields on the main form. The user will manually populate the [OpenDate], [OpenTime].
If the number is an existing number (and the user is simply adding a log entry to the incident number) then I want [EntryDate], on the subform to default to the system date/time ([EntryTime] should remain blank for user entry) while keeping [OpenDate], [OpenTime] unchanged. When the [EntryDate], [EntryTime] fields are populated on creation of a new incident number, I want the PK for the underlying table ([Log_ID]) to be generated.

automatically adding modified date/time to a record as it changes..I have a work log database for a team of people to keep track of workflow (documents in/out, stage in the workflow, owner of the record, etc.). I have a number of records that I want to automatically update a corresponding date/time field when it is changed. For example, one part of the workflow tracks a document through the approval of 5 different people. So I have a five records that are yes/no flags for approval and five records that are date/time for when it was approved. Right now my team is manually entering the five date/time stamps, but I'd like to have it automatically update when the check the "yes" box and update that field in the record.
