==SOLVED: See next post. ==
So bc of Time Zones, I have to add Hours(2) :
// Returns: thisRow.Created() rounded by nearest 5 minutes
Hours(2) + thisRow.Created().DateTimeTruncate(“hour”) + RoundTo(thisRow.Created().Minute(),5)
This returns 10:04:59 instead of 10:05:00.
If I leave out the Hours(2), however, it does work normal.
thisRow.Created().DateTimeTruncate(“hour”) + RoundTo(thisRow.Created().Minute(),5)
This returns 08:05:00
