sunrise/sunset times were recorded by the Mystery sites on Monday,
the same day you collected your own local sunrise/sunset data.
Time is the time people see on their clocks and
follow during their daily lives in each of the world's
24 time zones. Local time matches the sun's day/night cycle
in every time zone.
Universal Time is the same time everywhere
on Earth, in all of the world's time zones. Universal Time gives
us a world clock with one world time zone. Universal Time matches
standard local time in Greenwich, England (UT does not adjust for daylight saving time.)
