The following two entries are correct:

ws-drm2:~# zdump -v WET | grep 2005
WET  Sun Mar 27 00:59:59 2005 UTC = Sun Mar 27 00:59:59 2005 WET isdst=0 gmtoff=0
WET  Sun Mar 27 01:00:00 2005 UTC = Sun Mar 27 02:00:00 2005 WEST isdst=1 gmtoff=3600
WET  Sun Oct 30 00:59:59 2005 UTC = Sun Oct 30 01:59:59 2005 WEST isdst=1 gmtoff=3600
WET  Sun Oct 30 01:00:00 2005 UTC = Sun Oct 30 01:00:00 2005 WET isdst=0 gmtoff=0


ws-drm2:~# zdump -v Europe/London | grep 2005
Europe/London  Sun Mar 27 00:59:59 2005 UTC = Sun Mar 27 00:59:59 2005 GMT isdst=0 gmtoff=0
Europe/London  Sun Mar 27 01:00:00 2005 UTC = Sun Mar 27 02:00:00 2005 BST isdst=1 gmtoff=3600
Europe/London  Sun Oct 30 00:59:59 2005 UTC = Sun Oct 30 01:59:59 2005 BST isdst=1 gmtoff=3600
Europe/London  Sun Oct 30 01:00:00 2005 UTC = Sun Oct 30 01:00:00 2005 GMT isdst=0 gmtoff=0
ws-drm2:~#

But GMT0BST is not:

ws-drm2:~# zdump -v GMT0BST | grep 2005
GMT0BST  Sun Apr  3 11:59:59 2005 UTC = Sun Apr  3 11:59:59 2005 GMT isdst=0 gmtoff=0
GMT0BST  Sun Apr  3 12:00:00 2005 UTC = Sun Apr  3 13:00:00 2005 BST isdst=1 gmtoff=3600
GMT0BST  Sun Oct 30 10:59:59 2005 UTC = Sun Oct 30 11:59:59 2005 BST isdst=1 gmtoff=3600
GMT0BST  Sun Oct 30 11:00:00 2005 UTC = Sun Oct 30 11:00:00 2005 GMT isdst=0 gmtoff=0
