After some months, I just updated my local ikiwiki sources, and rebuilt
the Hurd web pages, <http://git.savannah.gnu.org/cgit/hurd/web.git/>.
I was confused, having switched to the new automatic (thanks!) --gettime
mechanism, why on some pages the timestamps had changed compared to my
previous use of --getctime and setting files' mtimes (using a script)
according to the last Git commit. For example:
community/weblogs/ArneBab/2008-08-02-gnu_hurd_and_x.html

I had a look at what git.pm is doing, and began to manually replay /
investigate:

That's all consistent.

That's different, and it matches what the new ikiwiki writes into the
HTML file.
Back to Git again, this time without specifying the file:

So, merges are involved there.
What (the new) ikiwiki code does, is use the timestamp when the merge was
done instead of the timestamp when the commit was done. Is this
intentional? Otherwise I could supply a patch.
