Manpages generated with the Perl module Pod::Man contain an embedded timestamp/date.

[[https://reproducible.debian.net/issues/timestamps_in_documentation_generated_by_podman_issue.html|Known affected packages]]

= Solution =

Get Pod::Man support SOURCE_DATE_EPOCH: see the bug Bug:801621.

Otherwise POD_MAN_DATE is available to be set, see below.

== Packages using debhelper ==

''A fix needs to be done in debhelper. See https://bugs.debian.org/780259#40''

== Packages calling pod2man directly ==

Set the environment variable `POD_MAN_DATE` to the desired date.

E.g. in `debian/rules` add:

{{{
SOURCE_DATE_EPOCH ?= $(shell date -d "$$(dpkg-parsechangelog -SDate)" +%s)
export POD_MAN_DATE = $(shell date -u +"%Y-%m-%d" --date="@$(SOURCE_DATE_EPOCH)")
}}}
