Subject: Second trends only go back 12 days 


While answering a quick question by Kiwamu, I noticed we only had second trends going back to 99050000 GPS time, May 27th 2011. 

Trends (I thought) were intended to be kept forever, and certainly longer than full data, which currently goes back several months.

Jamie will need to look into this.

 Our concept is to keep second trends for 1-2 months and minute trends forever. The scheme that Alan had worked out many years ago had it such that we could look back to 1998 and that the minute trends would be backed up somehow.

If its not working, we need to get Alan's help to recover the previous configuration.
