Clocks Don't Vary For Outer Space
SUNNYVALE, Calif. (AP) -- Earthlings across the nation moved their clocks ahead one hour Sunday for Daylight Saving Time.
But Lockheed Missile and Space Division scientists, keeping track of their orbiting Discoverer XI satellite, couldn't care less.
They never use regular clock time, no matter what the local time is.
They created a clock of their own called system time -- measured in seconds. By system time, 12 noon is 43200, or 43,200 seconds after midnight.
Actually system time is solidly linked with earthly clocks. It's really Greenwich time recorded in seconds instead of hours.
Midnight at the zero meridian in England reads 00000 on system time, and rolls around to 86400 by the next midnight.
