Then you could just do:

  $ git log --date=raw -g

Looking at making this trivial patch, though, it seems there is a bug
with the relative_date parameter. It is really a date_mode enum. In the
multi-line format, we feed it to show_date. But in the oneline mode, we
use it to decide whether to show the date, but then always pass the
"relative" date mode. So you get:

  $ git log --oneline -g origin/master | head -n 1
  e986ceb refs/remotes/origin/master@{0}: fetch origin: fast forward
  $ git log --oneline -g --date=relative origin/master | head -n 1
  e986ceb refs/remotes/origin/master@{2 days ago}: fetch origin: fast forward
  $ git log --oneline -g --date=raw origin/master | head -n 1
  e986ceb refs/remotes/origin/master@{2 days ago}: fetch origin: fast forward

Hmm. It seems to drop the TZ, too. I'll whip up a patch.

I guess my original "extra reflog header" isn't terribly useful, then:
you can always just pass --date=raw and parse it from the branch@{}
syntax.
