[gnome-control-center/wip/datetime-redesign: 13/13] datetime: Mark the time format strings as translatable

[Kalev Lember <klember src gnome org>]

commit 7c1005d94a319f213e1e4d5863b0d584da6a3cdd
Author: Kalev Lember <kalevlember gmail com>
Date:   Tue Sep 3 21:12:38 2013 +0200

    datetime: Mark the time format strings as translatable
    
    ... and add translator comments explainings what they do. The RTL
    languages are likely going to want to show them in a different order.
    
    We should eventually move to just using GnomeWallClock and/or
    g_date_time_format with %c that already have translated the time format
    strings. However, in case this doesn't make it in 3.10, mark the
    current strings in g-c-c as translatable to get some translation
    coverage.
