This is caused by Condor's transition to a new implementation of ClassAds, which started in the 7.5.x series. In the old implementation, CurrentTime was a magic attribute that would evaluate to the current unix time. In the new implementation, you use the time() function to get the current time. To ease the transition (until everyone changes their expressions), we insert a CurrentTime attribute (whose value is 'time()') into ads. This attribute now appears in the accountant log, and quill is attempting to insert it into the database. But it appears quill isn't expecting ClassAd functions in the values it reads from the accountant log.

I'm CC'ing the condor-devel mailing list. Does anyone know who's maintaining the quill code? It should be pretty easy to have it ignore the CurrentTime attribute.
