SGP/THWAPS/C1 - Time stamp of data record incorrect

Due to problems with the collector system, the datalogger was being time synched 
inappropriately.  This problem was intermittent and did not affect every time stamp.  The worst 
case time adjustments were approximately +/- 7 minutes.  These were infrequent and most of 
the time adjustments were less than 7 minutes.

None.
