Yes I believe the timer resets after the end of the day. If it's every twenty minutes you can provide your own track of time by establishing a static or module level variable that gets updated at every timer interval and check the elapsed time using this.

Say you set your timer to fire every second, then add the second to your static variable and check the number of seconds that have elapsed to the desired interval.

' at module level
Dim intSeconds As Long

' (set timer to fire every second)
' this inside timer event:
intSeconds = intSeconds + 1

If intSeconds > = 60 'interval set to every minute..

Call Do_My_Thing
intSeconds = 0

End If
