I'm doing this off of memory (I don't have my machine handy), but field "Remote Date and Time" will cause the remote time tags to sync when set to 1. We create a UDT:
.Year
.Month
.Day
.Hour
.Minute
.Second
.Sync
We use .Sync in the Remote Date and Time, then set it to 1 about every 15 minutes or so for 2 seconds. Something like that, like I said, this was off of memory.
