Firstly, what is the correct output? and secondly, what output are you getting?
We cannot see your screen or know what you are expecting so you have to tell us.

Solution 1

Use a TimeSpan. This will be much easier.

VB

Dim myTimeSpan as TimeSpan
myTimeSpan = TimerInfo.TotalTime - DateTime.Now
msgbox(myTimeSpan.TotalMinutes())

That is based on TimerInfo.TotalTime being the time of expiry.
