Bug#1126092: argparse-manpage: please make the output reproducible

[Chris Lamb]

Source: argparse-manpage
Version: 4.7-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
argparse-manpage generates nondeterministic manpages.

This appears to be a regression from version 4.5 which correctly used
utcfromtimestamp to parse SOURCE_DATE_EPOCH to a Python datetime
object. However, 4.7 uses fromtimestamp (cf. "utcfromtimestamp"), so
the generated manual pages differ depending on the surrounding timezone.

This is affecting at least the src:psutils and src:virtme-ng packages,
but there are likely more.

Patch attached.
