Transact SQL :: Convert Time In Specific Timezone To UTC (and Vice-versa)

In C#, I can convert UTC time to a specific timezone using:

TimeZoneInfo localTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Pacific Standard Time");
DateTime UTCTime = TimeZoneInfo.ConvertTimeToUtc(localTime, localTimeZone);

Is there any equivalent function in T-SQL (SQL Server 2014 / SQL Azure)?

Specifically, I want to be able to convert a time into UTC before inserting it into a table. Right now I am doing:

INSERT INTO Incident (IncidentDescription, dtOccurred)
VALUES (@IncidentDescription, DATEADD(hour, 8, @dtOccurred))

I don't want to hardcode "8" and I want it to adjust for daylight savings time (DST). 

Is there any concise solution that does not require me to define SQL functions or have lookup tables? I also don't want to use the difference between GETDATE() and SYSUTCDATETIME(), because the timezone of my server is not my local timezone.
