AIX : GMT to BST change
It’s that time of year again when the clock go forward. If your AIX
boxes didn’t do this automagically, check the /etc/environment file for
the following entry.
TZ=GMT0BST,M3.5.0,M10.5.0
If you only have
TZ=GMT0BST
….aix will not know when to do the change.
A reboot is necessary for the change to take effect
