Subject:
SGP/EBBR/E12 - Intermittent data loss
DataStreams:sgp5ebbrE12.b1, sgp30ebbrE12.b1, sgp15ebbrE12.b1
Description:
The datalogger at E12 EBBR reset it's time to Dec 3, 1999 on a periodic basis.  This 
occurred on 5/3, 5/15, 5/17, 5/18, 5/27, 6/5 and 6/6 of 2010. Each time this occurred we lost 
1-2 hours of data.

The datalogger was apparently at fault.  The problem has not re-occurred since the 
datalogger was replaced on 6/8/2010.
