time stamp error

The internal code that runs the MFRSR data logger
had a bug that occasionally caused the time stamp associated with the data to
be slightly in error.  This error is thought to be very small (say less than
30 seconds) and very infrequent.  (Unfortunately, we cannot give firm
estimates of the magnitude and frequency of the error). 

After 96/07/10 the problem was corrected.  Those who use the data before this
time should realize that the time stamp for each record of data might be
slightly in error.
