This is my Custom Function and I want to edit it


Thanks, this was really handy.

One improvement: Using floor is better than using round, otherwise you'll be off by one second 50% of the time.

Sounds reasonable enough. Done!

Not sure if I'm doing something wrong hereā€¦ I'm getting results that are seemingly 1 hour off. I'm in Central Standard Time (CST).

Get(CurrentTimestamp) = 10/13/2015 9:00:00 PM
UTC Timestamp = 10/14/2015 3:00:00 AM
Difference = 6 hours

But, when I apply the UTCOffset CF to the UTC timestamp, it brings it back to 10 PM, which is only 5 hours difference. Is there a daylight savings issue going on or something?

Nevermindā€¦ I was looking at a map that told me to subtract 6 hours when apparently the correct UTC is 5 hours for me. Daylight savings issue or something. Your custom function is working correctly, and perfectly for me, now that I solved my root problem!
