Subject: Re: [MTT devel] bogus timestamps in database

Yeah it might be good to touch base and see if there are any burning
fires that we need to put out.

For me it would have to be either next week or most likely the end of
August. :( The good news is that I don't have too much on my calendar
for next week. I'm available (prefer earlier in the week):
  M - Anytime
  T - 12 - 2, 2-4
  W - 10 - 11:30, 2 - 4
  R - anytime
  F - not available.
