    dateMenu: Get interval for the right timezone
    
    We're calling get_interval on tzA right now for both the tzA and tzB,
    this causes a critical error during shell startup:
    
    g_time_zone_get_offset: assertion 'interval_valid (tz, (guint)interval)' failed
    
    Fix this and use tzB to get the offset for timezone b.
