[gnome-settings-daemon] datetime: Add SetDate() function

[Bastien Nocera <hadess src gnome org>]

commit 9d94407a885f640df2aaf1b72b4b50f5907c5309

    datetime: Add SetDate() function
    
    So that we can set the date separately from setting the time.
    Setting the time is actually easier for us, as it's just an
    offset compared to the current time.
