The TSM Desktop Application requires your system time and timezone to be correct in order to function.

Ensure your system time and timezone are accurate for your location and with consideration to Daylight Saving if your location observes it. Your time may be correct when compared to your watch, but it would technically be incorrect if the timezone is an hour ahead/behind.

The easiest way to resolve a system time issue is to configure your system to set the time, timezone and Daylight Saving adjustments automatically on your behalf.
