Having natural noon between 12:00 at the eastern edge of a time zone to 13:00 on the western edge, is much preferable to 13:00 (east) and 14:00 (west). Even though the effects are the same for east on permanent DST and west on standard. They are very much detrimental—as in increases risk of sleep deprivation—for west on DST and public policy makers must take that into account when making decision.
