Re: NTP working but Switch has wrong Summer Time Start date

Your clock output states the Summer time starts on April 5th 2009, that's incorrect.

Please refer to this document on how to correct that setting:

I am in CST, which is -6 off GMT. When I try this, it is way off and it still says summertime starts April 5
