From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked 1 minutes ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.

Daylight

Sunset at DEN 6:21 pm MDT (00:21 UTC), at HDN 6:30 pm MDT (00:30 UTC) (civil twilight ends 6:58 pm MDT (00:58 UTC)). At 120 knots the arrival at HDN is before sunrise there (7:17 am MDT (13:17 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times.
