I think this does read better - "within the tzdata context" - which
simply needs a novice reader to be aware when one can mentally think UTC
or even GMT in a different context.

Displaying local times where one has sufficient information to show the
correct TIMEZONE is somewhat different to trying to guess that from a
simple offset on a single date string.
