    datetime: Use new g_date_time %z format modifier
    
    Use new %:::z format string to display timezone offset in a slightly
    nicer way. This is also needed for consistency with the timezone
    notifications from gnome-settings-daemon.
    
    Also bump glib dependency to 2.37.7 for the new modifier.
