WET/WEST is a little more precise and less confusing than GMT/BST (or
IST if you're of a more celtic nature, although this confuses people
living on the Indian subcontinent) although in tz-land, GMT has a
specific and pretty consistent definition. But it is generally a bad
idea to use it. People get confused.
