/*
|
||
|
This array lists a series of representative time zones and their
|
||
|
corresponding "meta-zone" labels.
|
||
|
|
||
|
The term "representative" here means that a given time zone can
|
||
|
represent others that use exactly the same rules for DST
|
||
|
transitions, UTC offsets, and abbreviations. For example,
|
||
|
Europe/Berlin can be representative for Europe/Rome,
|
||
|
Europe/Paris, etc., because these cities all use exactly the
|
||
|
same time zone rules and values.
|
||
|
|
||
|
Meta-zone labels are the user friendly strings shown to the end
|
||
|
user, e.g. "Mountain Standard Time". The values of this array
|
||
|
are keys of strings defined in Timezones.{language}.php, which
|
||
|
in turn are sprintf format strings used to generate the final
|
||
|
label text.
|
||
|
|
||
|
Sometimes several representative time zones will map onto the
|
||
|
same meta-zone label. This usually happens when there are
|
||
|
different rules for Daylight Saving time in locations that are
|
||
|
otherwise the same. For example, both America/Denver and
|
||
|
America/Phoenix map to North_America_Mountain, but the ultimate
|
||
|
output will be 'Mountain Time (MST/MDT)' for America/Denver vs.
|
||
|
'Mountain Standard Time (MST)' for America/Phoenix.
|
||
|
|
||
|
If you are adding a new meta-zone to this list because the TZDB
|
||
|
added a new time zone that doesn't fit any existing meta-zone,
|
||
|
please also add a fallback in the get_tzid_fallbacks() function.
|
||
|
This helps support SMF installs on servers using outdated
|
||
|
versions of the TZDB.
