Problem:

The front ends seem to have different gps timestamps on the data than the frame builder has when receiving them.

One theory is we have fairly been doing SVN checkouts of the code for the front ends once a week or every two weeks, but the frame builder has not been rebuilt for about a month. 

Current Action:

Alex is currently rebuilding the frame builder with the latest code changes.

It also suggests I should try rebuilding the frame builder on a semi-regular basis as updates come in.
