[PATCH v2 4/3] gitweb: Always call format_date with timezone parameter

[Kevin Cernekee <cernekee@gmail.com>]

From: Jakub Narebski <jnareb@gmail.com>

Make the timezone parameter mandatory.  This ensures that the *_local
fields are always populated with accurate information.

Also, delete an unnecessary call to format_date().

v2: Fix typos.  Remove unnecessary call.  Remove default "-0000" tz value.
Rebase on top of my patch 3/3 (as applying -1/3 then 1/3 would create a
merge conflict).
