Subject:	SGP/MFRSR/E6 - Possible date/time corruption
DataStreams:	sgpmfrsrE6.a0, sgpmfrsrE6.b1
Description:	Incorrect capacitors in the loggerboard during this time resulted in corruption of the raw data. Date and time information as well as logger and head ID were incorrectly reported for some records. Users of these data should be alert for unexplained discontinuties in the .a0, and .b1 level data set.
