Re: Weird DST date calculation issue - RESOLVED
Lucky for you this worked. It doesn't work for me because I need to keep the time the same. (If someone wanted 3.15.2010 at 6:00pm, it has to stay that way) The DATEADD Function is great, but it resets the time back to 12:00:00 AM. I actually had to parse the data, set aside the time, add the days and then put it all back together again in the end. Works well, but I hate all the extra workflow.
