PVC/UHSAS/S1 - Problem with time fields

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.

Use the data after averaging over longer periods.	
		
Do a careful match 
of spikes 
with other datastreams to figure out the time differences.
