How to Configure NTP on Checkpoint SecurePlatform?

This is an old problem, but maybe not everyone knows this:
If you work with NTP servers sync on SPLAT, you should also set the timezone to get correct date/time and daylight saving. Unfortunately, this can't be done in the WebUI. So first configure your NTP servers in the WebUI. Then access the command line and execute sysconfig. Use option 4 to go to time settings and then option 1 for setting thetime zone according to your location.
Verify that you got the correct time using the WebUI.
