Old-style links such as US/Eastern are no longer included by default, but are available in the tzdata-legacy package instead.Just thought I'd share. I wonder if other distributions / platforms / libraries will follow suit. What do y'all think?See: <https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/2058249> <https://stackoverflow.com/questions/78180695/unrecognized-time-zone>
I've been looking at that to reduce Cygwin CI and embedded build server setup overhead by limiting base install data to:- only the zones in zonenow.tab; - optionally those in zone1970.tab not in zonenow.tab; - additionally those in zone.tab in backward, and/or backzone; - possibly those not in zone.tab, only in backward, and/or backzone; - additions those in posix subtree, or right subtree.
As tzdata maintainer, I would like to discuss on this list first, to take advantage of a wide variety of experience in different environments with different practices and requirements, before making more definite proposals on the public list.
Please see the attached log for prioritized subsets of tzdata for consideration:#1 minimal zones required to set the time as it is used around the globe, which may require using a different zone id (name) than before, and will be correct from release onwards, but possibly not exactly the same historically
#2 extra zones whose clocks have agreed since 1970 and provides correct historical times for the zone based on those locations from 1970 onwards
#3 zones which have more, but possibly questionable, historical data#4 backward compatibility links to other zones, like legacy country based directories or regions, or because of renames, splits, data proved uncertain, never really correct, never used in the region, was the same as surrounding or adjacent regions, or was part of a different country
#5 legacy and historical zone ids Counts of each are: pri 1 91 zones src zonenow.tab pri 2 221 zones src zone1970.tab pri 3 132 zones src backzone pri 4 113 zones src backward pri 5 41 zones src filesThere are also the subtrees for posix, which duplicates the base data, in contrast to the right subtree which has the same zone names, but provides TAI-10s time_t counting leapseconds (currently UTC+27s) ignoring 86400s/day.
The balance is between a proliferation of packages and reasonable selections of data, so discussions will be pursued, opinions solicited, possibly debated.
The first package split I propose is tzdata-right, which will include both the right and posix subtrees, as few outside the physics communities may need this, and we don't know if anyone uses it on Cygwin: yet!
Next for consideration is where the legacy and historical #5 ids fit?Should they be split into a separate package, or included in a package for servers that possibly still use original zones, or require specific GMT offsets, like ships at sea?
Then we should look at what to do with the backzone #3 and backward #4 zones that offer more historical data, plus backward compatability ids and links, which may be useful to the astrological community, and on user desktops. The backward links could be replaced by instructions taht say if you are using link id, use zone id instead.
The zones in #2 allow recent history to be followed and a large number of zones that most desktop users are likely to expect to have available. For me, this includes my local America/Edmonton zone which tracks provincial variations in DST observance over the last half century before DST was more standardized.
The zones in #1 are limited but reduce minimum install footprint for CI and servers that may use few zones other than the built in UTC default.
For me, that means I would have to select America/Denver to get MT with NA DST.The practice would be similar in Europe: most Europeans would have to select Europe/Berlin, as that is the most populous city using that time zone. Would this be a good place to add #5 in case legacy zone ids are used on server builds?
What would the impact on tzset conversion from Windows to Olson tzdb be? We would probably have to add all of these in to any minimal install. I think I looked at that somewhere, sometime, not too long ago.All questions, comments, and suggestions will be greatfully received and responded to.
