I've been reading a lot of NASA pages on the shuttle recently and was reminded once again that NASA seems to use "GMT" instead of "UTC" to label their timelines. Do any of you know why? That brings up another question - has a leap second ever occurred during a NASA mission and did it have any effect on timing? Or is everything done in Mission Elapsed Time (MET) - one more example of a leapsecond-less timescale. /tvb http://www.LeapSecond.com
