For background information: the purpose of storing them in a tzfile is
to allow that tzfile to be used as a template for dynamically creating
timezones with the same rules but other offsets. This is used for the
timezone named "posixrules" - which is a US timezone (America/New_York)
by default - to generate timezones for POSIX timezone strings that don't
explicitly specify their daylight rules.
They should not be used for normal interpretation of a timezone.
