Time Clock Events and daylight savings time

Since DST now happens earlier then it used (by approx 3 weeks) I have time clock events that are now starting to late now. Example, perimeter lights on the outside of the house now come on when its dark and not before its dark. How does the main repeater know when to go into DST mode? I have it checked off in the Inclusive software and the main repeater is on the network. I'm stumped as to where the main repeater gets its time info from? I would have thought that it came from the network but it doesn't adjust with the time change.

Any help is greatly appreciated.....

DST is configured in the PC software. You can set it to whatever you'd like. It's in the same screen as your project's location. Use the Settings->Location menu option, and then 'Show details'.
