# Checks how cgit shows a commit date, which is either an age relative to now
# or a calendar date in the format the config names, and in which timezone.
# The config is rewritten between cases so that each one names only the
# settings it is about and leaves the rest at their defaults.

# The repo holds the commit mkrepo dates in 2005 at +0200, an old one at +0000
# and a fresh one, so that the log shows both the relative rendering and the
# calendar fallback that takes over past the two week cutoff. Each tag is
# dated in the upper half of an age bucket, where the bucket below would take
# it if its bound slipped, and one is dated a day from now. The minutes stop
# 20 seconds short of 90, which a slow run still rounds to.
