You can download software that will synchronise your computer clock to a server linked to an atomic clock. I am now using
http://www.clock-sync.com I had to dump Atomic 2.5 because it did not take account of the fact that the UK and US do not always make the time change on the same weekend. Clock-Sync allows you to set your time zone, and even allows you to offset your clock setting by the desired number of minutes - in my case, zero.
Trivia question: What's the longest month of the year?
Answer: October, because it has 31 days and is also the month when clocks are retarded by one hour, and is therefore one hour longer than the other months with 31 days.
