Subject:	SGP/EBBR/MET/SWATS/E9 - Incorrect Timestamp
DataStreams:	sgpmetE9.00, sgp30ebbrE9.b1, sgpswatsE9.a1, sgpmetE9.b1, sgpswatsE9.01, sgpswatsE9.b1, sgpswatsE9.00, sgp15ebbrE9.b1, sgp5ebbrE9.00, sgpebbrE9.00, sgpebbrE9.01, sgp5ebbrE9.b1
Description:	The data collection computer lost communication with GPS for the affected time period at this site. The instrument time is not correct causing the data to be up to 30 minutes behind actual time by the end of the affected time period. The time shift is not linear and no known time correction could be applied to the affected data streams.
