Daylight Saving Time serves no purpose and imposes unnecessary risk on the American public.
See this article in TIME for some arguments: http://time.com/3549442/daylight-saving-time-traffic-deaths/ and this: http://www.businessinsider.com/daylight-savings-time-bad-health-effects-...
I suggest that we stay on DST offsets year round so that the sun is up later, even in December and January. The sun being up at 6am serves very little purpose, however the sun being up at 5pm makes the evening rush far safer, and raises moral since the day doesn't seem over before most of us have even left our desks.
Please make the year round time zones: Eastern -04:00, Central -05:00, Mountain -06:00, Pacific -07:00, Alaska -08:00, Hawaii–Aleutian -09:00.
