This need correcting immediately.

BST = British Summer Time   (NOT 'Standard' time).

the normal timezone in the UK is GMT (Greenwich Mean Time, the "base"
time for all timezones).  BST is GMT+1 and applies between the last Sunday
in March and the last Sunday in October (01:00 GMT in both cases).  (EU
Seventh Directive 94/21/EC defines these dates in all member states)

Your timezone variable should read:-


(the reason that there's a '2' at the end is because the time to switch
out of the alternate timezone is based on the time in the alternate
timezone, not the normal timezone) (the reason it says 'BST-1' is just
the oddness of the way UNIX denotes timezones.  BST _is_ ahead of GMT).

Hope this helps

(BTW, is the TZ variable correct in the environment that the Samba
Daemon runs in?)
