[empathy] Display relative time to user

[Pierre-Luc Beaudoin <plbeaudoin src gnome org>]

commit c40737394bff5c27daea7e4ee08f240224475904
Author: Pierre-Luc Beaudoin <pierre-luc pierlux com>
Date:   Tue May 26 15:38:32 2009 -0400

    Display relative time to user
    
    The time of the geolocation update is displayed relatively to
    current time (1 min ago, 3 hours ago).
    
    The function just prints ("in the future") for debugging purpuses
    for time in the future.
