No need to break the time. Try with "TZ=Australia/Canberra", which
currently has summer time.

I'm able top reproduce it here on TL 2023.

I've uploaded TL2023 to experimental. Are you willing to test if the issue
is solved there?

Beware: the package is not complete yet, there is not context package being
compatible to texlive-binaries.


Sorry, I've just noticed that I forgot to include the test.tex file.
Here is it (this is the simplest one as possible):

\documentclass{article}
\begin{document}
.
\end{document}

If you installed TL2023 on one of your machines, could you try to
reproduce the bug after "export TZ=Europe/Paris", for instance?

Otherwise, I can try (but it will be a bit complex to upgrade the
packages to experimental and downgrade again after the test).

Bug#1041631: texlive-xetex: CreationDate in the generated PDF file is incorrect by 1 hour in some timezones

[Vincent Lefevre]

Package: texlive-xetex
Version: 2022.20230122-3
Severity: normal

The "CreationDate:" field in the generated PDF file is incorrect by
1 hour in the Europe/Paris CEST timezone (= UTC + 2).

Example:

$ export LC_ALL=C
$ date && xelatex test.tex && pdfinfo test.pdf | grep Date:
Fri Jul 21 16:09:39 CEST 2023
This is XeTeX, Version 3.141592653-2.6-0.94 (TeX Live 2022/Debian) 
(preloaded format=xelatex)
 restricted \write18 enabled.

It looks like as if it were the winter time (UTC + 1).

Same issue in the Europe/London and America/New_York timezones.
For instance:

$ export TZ=Europe/London
$ export LC_ALL=C
$ date && xelatex test.tex && pdfinfo test.pdf | grep Date:
2023-07-21T15:22:17 BST

But the behavior is correct for America/Guyana and
America/Argentina/Buenos_Aires.

This could possibly be related to the daylight saving time.

Note that pdflatex does not have any issue.

-- Package-specific info:
IMPORTANT INFORMATION: We will only consider bug reports concerning
the packaging of TeX Live as relevant. If you have problems with
combination of packages in a LaTeX document, please consult your
local TeX User Group, the comp.text.tex user group, the author of
the original .sty file, or any other help resource. 

In particular, bugs that are related to up-upstream, i.e., neither
Debian nor TeX Live (upstream), but the original package authors,
will be closed immediately.

   *** The Debian TeX Team is *not* a LaTeX Help Desk ***

If you report an error when running one of the TeX-related binaries 
(latex, pdftex, metafont,...), or if the bug is related to bad or wrong
output, please include a MINIMAL example input file that produces the
error in your report.

Please run your example with
(pdf)latex -recorder ...
(or any other program that supports -recorder) and send us the generated
file with the extension .fls, it lists all the files loaded during
the run and can easily explain problems induced by outdated files in
your home directory.

Don't forget to also include minimal examples of other files that are 
needed, e.g. bibtex databases. Often it also helps
to include the logfile. Please, never send included pictures!

If your example file isn't short or produces more than one page of
output (except when multiple pages are needed to show the problem),
you can probably minimize it further. Instructions on how to do that
can be found at

http://www.minimalbeispiel.de/mini-en.html (english)

or
