[PATCH 5/8 v6] gitweb: add a get function to compliment print_local_time

[Jakub Narebski <jnareb@gmail.com>]

From: John 'Warthog9' Hawley <warthog9@kernel.org>

This adds a get function (named format_local_time) for print_local_time,
so that the basic function can be used outside of their straight printing
operation.
