Subject: | PVC/UHSAS/S1 - Problem with time fields |
DataStreams: | pvcaosuhsasS1.a1 |
Description: | During the deployment the instrument time for the UHSAS was not automatically synched and tended to drift fast relative to the time corrected by a time server. The time of the data in the files is about 20 to 220 seconds fast. This has been determined by comparing the time of spikes in UHSAS CPC data. The Documents show the time of the peaks used to approximate the error in the time. About 2 peaks a week were chosen to compare. |
Suggestions: | Use the data after averaging over longer periods. Do a careful match of spikes with other datastreams to figure out the time differences. |
