I'm getting an xml which has all dates in GMT. The problem is that for an entry with date in Sumer Time period i'll have to add 3 hours in order to make it GMT +3, but when the date of the entry is in the Standard Time period, i'll have to add 2 hours, to make it GMT +2.
For example, if an entry has starting date as 1/7/2010, before adding it to my db i should add 3 hours. But if the event stars in november (1/11/2010) i should add 2 hours.
Is it possible to identify with php if a date is in Standard or Summer Time?
