Since revision #6273, System.TimeZone now takes the daylight saving time 
into account.

It's not technically the timezone anymore, but I can't change the 
property name. And concretely daylight saving time changes your timezone 
after all.

Note #1: knowing the current daylight saving time needs a GNU C library 
extension coming from BSD.

Note #2: this f.....g daylight saving time coming out of the brains of 
crazy politicians wanting to control time and who certainly had smoked 
illegal products should burn in fire.
