[TRNSYS-users] Definition of the Time

Dear Trnsys users

I am looking for the definition of the time used in the Meteo files and its relation with the solar time
I supposed it is the Local Standard Time = Apparent Solar Time - Equation of Time - (Local Standard Time Meridian° - Local Longitude°)/15 with the longitude increasing to West.

It seems, after some tests, that the Trnsys do not take in consideration the daylight saving time (quite no difference in time for solar azimuth at south between summer and winter)
How can we consider it easily in Trnsys (for instance: move automatically the schedules one hour earlier from april to September) ?

Thank you for your help
