Follow-up Comment #1:

Hi Christian,

Colin Watson reported and fixed this issue in one of the first commits after
_groff_ 1.23.0 was tagged.  It is already integrated into the Debian packages
thereof.

You might wish to backport his change.

Testcase (on Cygwin):


$ groff --version
GNU groff version 1.23.0
...
GNU troff (groff) version 1.23.0
GNU grops (groff) version 1.23.0

$ echo $TZ ; date -Is
Europe/Berlin
2023-08-29T13:55:10+02:00

$ date -d '2023-01-01 UTC' +%s
1672531200

$ date -d @1672531200 -Is
2023-01-01T01:00:00+01:00

$ echo | SOURCE_DATE_EPOCH=1672531200 groff -Tpdf \
| grep -a 'Date'
5 0 obj << /CreationDate (D:2023010101+02'00')
/ModDate (D:2023010101+02'00')


Observed:
The timestamps use current timezone instead of UTC.
The time may be incorrect by one hour because current DST offset is used.
This may break reproducible builds.

Expected:
If SOURCE_DATE_EPOCH is set, UTC should be used regardless of current TZ.

Workaround:


$ echo | TZ=UTC SOURCE_DATE_EPOCH=1672531200 groff -Tpdf \
| grep -a 'Date'
5 0 obj << /CreationDate (D:2023010100+00'00')
/ModDate (D:2023010100+00'00')
