See if it helps you.
To simulate the ticket creation date, I set the following variable:
Set(
gblTicketDateTime,
DateTimeValue("08/31/2022 22:10","en")
)
Now, in the timer control:
Duration property:
DateDiff(gblTicketDateTime, Now(), Milliseconds)
Text property:
Text(
Time(
0,
0,
(Self.Duration - Self.Value) / 1000
),
"hh:mm:ss"
)
Result:
