Just though I would post this, in case anybody didn't know.
Summertime starts tonight, the clocks go forward one hour.
If you have transport or other timed events tomorrow, don't be late.
The rule is: Summertime starts 02:00 CET last Sunday in March, ends 03:00 CEST last Sunday in October.
Applies to all European countries EXCEPT Belarus, Russia and Iceland, which don't use Summer Time.
