I think the posting problem is related to the dreaded Daylight Savings Time. The server on which this site is hosted perhaps did not have a patch to ensure proper realization of DST. It, therefore, changed over today, as did my computer at home. I have Windows XP but I never installed Service Pack 2 so I couldn't download and install the DST patch. I woke up this morning to find the computer had changed the internal clock, setting it ahead an hour.
