how to set correct time?

[Rory Campbell-Lange <rory@campbell-lange.net>]

I foolishly don't know how to set the correct time for my system clock.
The timezone is correctly set to London/England, but the time is about 6
hours out (date reports the time in 'BST' - I presume this is "British
Standard Time").

I tried using the date command but nothing happened.

Thanks for any help
Rory
