In calculating the amount of time that an eventually patched patch remains unpatched (say that three times fast), I was not CASTING to a BIGINT, but rather leaving it at the default SQL INT. Ergo, if you patch patches after 90 days or so, you'd get a non-fatal SQL error from ldms_core. You'll want to upgrade, from here: http://www.droppedpackets.org/scripts/ldms_core

For everyone else, nothing to see here, move along. I did some code clean up but haven't really started on the big stuff for the 3.0 release.
