Re: GSC 3493-1324

A one day error is not likely for this date.  That is nothing funny has
happened to the computer clocks this year except that  I have caught the
TOM1 computer jumping several hours.  This seems to happen when the
computer has been sitting idle for a day or so.  If the computer jumped
several hours, then the pipeline would simply not find stars.  This also
holds true for a one day off clock.  The star fields would be unlikely to
match close enough and no data would come out of the pipeline.  Since there
is lots of data, one can look at known variables in the data and compare
them to known phases.  Should give a clue.

While anything is possible, I think a one day error is unlikely.
