If you look between midnite and 3AM EST, you'll see that the post order is screwed up. This is a glitch in the software that we noted and reported to UBB. It will be fixed in the next release.
Here's my suspicion:
Our server is PST, our messages are ordered by EST. The software mistakenly orders by EST time and PST *DATE*. Therefore a post made at 1AM 12/2 is ordered as 1AM 12/1 (since the server is still showing the previous day). At 3AM, the PST server clicks over to 12/2 and the ordering automatically falls into place correctly.
Even during these three hours, you should be able to readily identify new posts by the color difference in the folder icon to the left of the threads.
