Subject: FrameBuilder fails in a new way 

Since Leo was trying to demo his LIGO Data Listener code, he noticed that there was and NDS2 issue. The NDS2 guy (JZ) noticed that the FrameBuilder had an issue.

We investigated. At 4PM on Dec 31, the GPS timestamp of the frame file names started to be recorded wrong. In fact, it started to give it a file name matching the correct time from 1 year in the past.

So that's our version of the Y2011 bug. Here's the 'ls' of /frames/full:

controls@fb /frames/full $

The culprit is the directory who's name starts out as 9463 whereas it should be 9779.
