[Nmh-workers] exmh patch to fix local time display in date header

[Robert Elz]

Following on some discussions on the nmh list, I
observed a problem with the local time display
in exmh (which is doing what I think should be the
default for nmh - that is, displaying both th
original (sender) Date: header with the local time
appended.

Except that it wasn't working in the case that
raised the issue on the nmh list - messages with +0000
listed in the Date header - nor for that matter, any
other +NNNN zone (it worked fine for -NNNN and for
the alphabetic zone names from rfc822).

This looks like an underlying problem in tcl's
clock scan code - but in the case whre no format
string is provided, which the tcl doc says is
obsolete, and shouldn't be used.  Giving a suitable
format string (after a little massaging of the
input string to remove comments) seems to make it work.

Below is a patch that should fix it - along with not
displaying any local time in the case where the zone is
given as -0000 (ie: unknown).

ps: Note that there's actually still a bug in the
unusual case where the sender's, and local, timezones
are different by exactly 24 hours - but that's so rare
it probably isn't worth fixing.
