Subject: | SGP/MET/E21 - TimeCheck Error |
DataStreams: | sgpmetE21.b1 |
Description: | Starting on 2010-06-07 the E21 system clock started drifting until the problem was corrected on 2010-06-29. The maximum daily offset reported in the collection logs were: Jun 7 offset: -5.04 Jun 8 Offset: -267.449039 Jun 9 Offset: -541.038624 Jun 10 Offset: -814.469141 Jun 11 Offset: -1076.862114 Jun 12 Offset: -1350.330223 Jun 13 Offset: -1623.639335 Jun 14 Offset: -1897.047754 Jun 15 Offset: -2170.552312 Jun 16 Offset: -2422.130746 Jun 17 Offset: -2684.607495 Jun 18 - Jun 22 (unknown) Jun 23 Offset: -4204.730579 If the E21 system clock drifts the E21 Datalogger clocks will be set to the same incorrect time. The met data will be correct but the corresponding time stamp cannot be accurately known or simply corrected. |
