First, currently the localtime part is needed only to have "atnight"
warning. I wonder if with 'localtime' feature enabled gitweb should
show GMT time, or is it not necessary.
With 'localtime' it could simply be
Thu, 17 Mar 2011 18:28:57 -0700
either marked with "atnight" as whole, or only time (see below).

Second, from above description it is not clear which part of date is
marked with "atnight" style when 'localtime' feature is enabled.
Is the whole localtime part marked, and GMT left not marked:
Thu, 17 Mar 2011 18:28:57 -0700 (01:28 +0000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Or perhaps only the local _time_ is marked with "atnight" style:
Thu, 17 Mar 2011 18:28:57 -0700 (01:28 +0000)
^^^^^^^^
Or perhaps whole date now uses "atnight" style:
Thu, 17 Mar 2011 18:28:57 -0700 (01:28 +0000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'm not sure if we need to write about it being RFC2822-like format;
it is just implementation detail.
Perhaps
+# Returns formatted date and time, outputs HTML.
It is important if it is HTML or not, to know if it needs to be esc_html
or not.

See comment below.

I would really prefer to split this patch in two: first refactor
date-printing code, introducing and using timestamp_html subroutine,
with no changes in output, and leave introducing 'localtime' feature
for a second patch.

Why not use
my ($date, $use_localtime) = @_;
and $date->{'rfc2822_local'} instead of $date{'rfc2822_local'}?
Also with current code the calling convention for timestamp_html (or
format_timestamp_html, or format_date_html) looks like this:
print " [" . timestamp_html(\%ad, 0) . "] "
or
print timestamp_html(\%wd, 1)
This would require anyone who stumbles upon on a calling site to have
to refer to definition of this function to understand it.
In many other places we use "named parameters" for such boolean flags;
then the calling convention could be
timestamp_html(\%date)
or
timestamp_html(\%date, -long=>1)
(or -localtime=>1, or -atnight=>1, etc.).
We can also/instead provide timestamp_short_html and timestamp_long_html
so one can write
timestamp_short_html(%date)
and
timestamp_long_html(%date)
