export TZ=UTC has always worked.

With regards to GMT != UTC I think we have the situation globally that
legal time is based on astronomical time but we all set our clocks by
atomic time. So Europe/London is in theory GMT in the winter and GMT+1 =
British Summer Time in the summer but we set our clocks to UTC in the
winter and UTC+1 in the summer and no-one cares about the difference until
we have to implement a leap second.
