Alternatively, a <replaceable>time_zone_name</> can be given, referencing

that zone, and if so, the appropriate meaning is used &mdash; that is,
400+
the meaning that was currently in use at the timestamp whose value is

402+
wasn't current at that time, or the oldest meaning if it was used only

abbreviations whose meaning has historically varied. It is also allowed
405+
to define an abbreviation in terms of a zone name in which that
