It is important that all computers you will be using have the same time zone settings. This is specially important if using the Internet time servers.
To verify that all computers are on the same time zone, click on the time / date as shown below to pop up the Time / Date Window. Then click on the "Change date and time settings..." link seen below.
Then if the Time Zone displayed (highlighted in yellow below) is not correct, click the "Change time zone..." button and select the proper time zone for your location. Do this on all computers that will be networked together with with TimeClockWindow.
