I’m having an issue on how to add the Offset to the EventDateTime. Is there a way to do this? I would convert it to a decimal number but cannot because 5:30 is not 5.3 hours, it’s 5 hours and 30 minutes.
The data is shown below with the expected output. Please help if possible.
Sample Data:

Not exactly pretty, but it works…
DECLARE @eventDateTime VARCHAR(50), @offset varchar(10)SET @eventDateTime = '2020-09-30 5:00AM'SET @offset = '-5:30'SELECT CASE WHEN @offset LIKE '-%' THEN CONVERT(DATETIME,@eventDateTime) - REPLACE(@offset,'-','') ELSE CONVERT(DATETIME,@eventDateTime) + REPLACE(@offset,'+','') END
