Hello. I useĀ debian-live-7.0.0-amd64-gnome-desktop. And it has error in Time Zones Settings. System Time changes during installation. It`s possible that date can changes too.
for example: when i boot from livecd i change location settings from London to Russia (Asia), Krasnoyarsk and my system time changes from 20:20 to 04:20 example2: when i install version to hdd my system time changed from 00:50 to 08:50 i suppose that error present in other versions. same problem i noticed in Scientific Linux. i use ROSA Desktop Fresh and looks like it hasn`t error. in my own apinion: date and time must be stay as it set in local pc, while time zones parameters sets in configs. -- Maxim Markov
