GMT 1. Time is written according to the European system. For example, 2 pm is written 14.00. Daylight saving time is used, i.e. the clocks are moved forward 1 hour at 2 am on the last Sunday of March and are moved back to normal time at 2 am on the last Sunday of October.
Dates are often written in the following order: year, month, day, e.g. 12 October 2009 is written 2009-10-12 (or just 091012), or 12/10 2009. American visitors in particular should take note that 12/10 does not mean the 10th of December.
