It looks like it...  To be more precise, I looked at the documentation
for `date-time-zone-offset', which referred to the TZ environment
variable, and then I looked up the tzset() man page which said that a
":Foo" value for TZ will make it use the "Foo" zoneinfo file -- so it
should be fine assuming that "GMT" is always present.
