Exactly, and that would be communicated how, in a brief manner - as Mark used in "Mondays at 8:00 PT"
On the other hand, if the meeting took place in Berlin, some would say "Mondays at 8:00 CET" while others would say "an Montagen um 8:00 MEZ".
Which is a case for placing such time zone abbreviations in localisation frameworks such as CLDR rather than in the tz database.
Yes, it is. To what ID in the IANA time zone database would a localization database connect to?
And, in fact, there are time zone abbreviations in CLDR.
Metazones, for those who don't already know, are things that group zones that are "the same timezone" Can you point to a definition?
(e.g. the two dozen or so U.S. and Canada -05:00 EST/-04:00 EDT zones are all "America_Eastern", your CET/MEZ/whatever are all "Europe_Central", etc) together, and are the key used to look up the localized timezone names and abbreviations. They include a standard and daylight offset, and of course a name, but _not_ the question of whether DST is used at all, or what the specific changeover dates for it are.
The data is at http://unicode.org/repos/cldr/trunk/common/supplemental/metaZones.xml, <timezone type="Africa/Algiers"> <usesMetazone to="1977-10-20 23:00" mzone="Europe_Western"/> <usesMetazone to="1979-10-25 23:00" from="1977-10-20 23:00" mzone="Europe_Central"/> <usesMetazone to="1981-05-01 00:00" from="1979-10-25 23:00" mzone="Europe_Western"/> <usesMetazone from="1981-05-01 00:00" mzone="Europe_Central"/> </timezone>
Looks like partial duplication of IANA data: ftp://ftp.iana.org/tz/data/africa Zone Africa/Algiers 0:00 Algeria WE%sT 1981 May 1:00 - CET
Really, metazone specification itself seems like it _should_ be the domain of tz rather than CLDR. But it would require an incompatible extension to the syntax of the timezone source files.
Something close might be there if the acronyms would be selected differently. E.g. using: https://tango.info/wiki/Internationalized_time_point_unique_time_zone_abbrev...
