Re: [tz] No time zone on Solaris servers

On 8/26/22 10:06, W CUI wrote: > We are running 64-bit Solaris as showing from the "isainfo -v" output. Fine, but Solaris 10 /usr/bin/date is a 32-bit executable and is dynamically linked to a 32-bit C library /lib/libc.so.1 that is reading your TZif files. Presumably your "isainfo -v" outputs something like this: 64-bit sparcv9 applications vis2 vis 32-bit sparc applications vis2 vis v8plus div32 mul32 and the last two lines are what matter here. I expect that 64-bit Solaris 10 apps don't have this problem. To find out whether I'm right, you can run '/usr/bin/sparcv9/ls -l' on a new file and look at the resulting timestamp. Regardless, if this issue is a real problem for you then it's time to file a bug report with Oracle (you can tell them I sent you :-). And in the meantime you can get by with 'zic -b fat'.

No time zone on Solaris servers
by W CUI Aug. 25, 2022

Aug. 25, 2022

Hi list, We downloaded tzdb2022c and compiled it on a Solaris 10 server with TOPDIR=/newtz and other default config parameters. After compiling is finished, the zoneinfo directory is copied to an other Solaris server, then the date command does not show any time zone on the host. It seems the server is at UTC time zone. Can anybody point me on how to fix it? Thank you very much! Wei Sent from Yahoo Mail for iPhone

It should also be pointed out that Wilson Tucker wasn’t even living in Australia when he was elected (via weird voting preference deals that have resulted in calls to update the WA voting legislation).

Add option to act like global-tz
by Paul Eggert Aug. 18, 2022

Aug. 18, 2022

I wangled a bit of free time and wrote the attached proposed patch, which adds an option that causes 'make install' to generate time zone data (TZif files) that are byte-for-byte identical to what Stephen Colebourne's global-tz currently generates. This is done via a few lines of awk script. The idea is to give an option to distros that prefer a separate Zone per ISO 3166 country, just as we already have build-time options for rearguard/vanguard form, TZif truncation, leap seconds, etc. I haven't installed this in the development database. Comments welcome as usual.

time_t truncation occurrence in tzcode
by Jan Engelhardt Aug. 18, 2022

Aug. 18, 2022

Due to an update of the Coverity Scan analyzer itself, it has identified a new issue in timezone code. In version 2022c (the excerpt is copypasted from an own project, so line numbers don't mean much), it has flagged: <<< 1757 while (year_lengths[isleap(y)] <= idays) { 1758 int tdelta = idays / DAYSPERLYEAR; 1759 int_fast32_t ydelta = tdelta + !tdelta; 1760 time_t newy = y + ydelta; 1761 register int leapdays; 1762 leapdays = leaps_thru_end_of(newy - 1) - 1763 leaps_thru_end_of(y - 1); 1764 idays -= ydelta * DAYSPERNYEAR; 1765 idays -= leapdays; 1766 y = newy; 1767 } 1768 1769 if (!TYPE_SIGNED(time_t) && y < TM_YEAR_BASE) { CID 1491244 (#1 of 1): Use of 32-bit time_t (Y2K38_SAFETY) 1. store_truncates_time_t: A time_t value is stored in an integer with too few bits to accommodate it.

Re: [tz] tzdata 2022b and 2022c location

However, the latest release there is 2022a. Are 2022b and 2022c not officially released or may be changed location? I suspect that you're talking about ICU's files concerning time zones as opposed to the tzdata files themselves, as the repository you mention stopped mirroring tzdata files after tzdata 2011k. ICU is downstream from tzdata and an ICU forum would be a good place to ask about ICU's status. A request for ICU to update to match tzdata 2022b (and 2022c) is here: https://unicode-org.atlassian.net/browse/ICU-22118 and I expect you can monitor and/or comment there. Currently nobody is assigned to the task.

[tz-announce] 2022c release of tz code and data available
by Paul Eggert via tz-announce Aug. 16, 2022

Aug. 16, 2022

The 2022c release of the tz code and data is available. This release reflects the following changes, which do not affect timestamps unless your system has the awk bug mentioned below: Briefly: Work around awk bug in FreeBSD, macOS, etc. Improve tzselect on intercontinental Zones. Changes to code Work around a bug in onetrueawk that broke commands like 'make traditional_tarballs' on FreeBSD, macOS, etc. (Problem reported by Deborah Goldsmith.) Add code to tzselect that uses experimental structured comments in zone1970.tab to clarify whether Zones like Africa/Abidjan and Europe/Istanbul cross continent or ocean boundaries. (Inspired by a problem reported by Peter Krefting.) Fix bug with 'zic -d /a/b/c' when /a is unwritable but the directory /a/b already exists. Remove zoneinfo2tdf.pl, as it was unused and triggered false malware alarms on some email servers. Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2022c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2022c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2022c.tar.lz The following convenience links are also available, although they may point to the previous release until the relevant caches are refreshed: https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz https://www.iana.org/time-zones/repository/tzdb-latest.tar.lz Links are also available via plain HTTP, and via FTP from ftp://ftp.iana.org/tz/releases with the same basenames as above.

If your tzdata parser does not yet support negative DST offsets or times past 24:00, or if it insists on a 'pacificnew' file that is no longer present, this release's data entries can be turned into a rearguard-format tarball that should work even with these older parsers. This is intended to be a temporary transition aid for these parsers. To generate a rearguard-format tarball, obtain the full distribution as described above, and run the command 'make DATAFORM=rearguard tailored_tarballs' on a development host. Or you can run 'make rearguard.zi' to generate a single file that can be fed directly to a parser that works like 'zic'.
