Word from a Washington, DC-area AOL subscriber is that their outgoing electronic mail is still being marked with "EST" time stamps that are an hour behind wall clock time. Do folks know of other high-visibility bobbles of the change in US DST rules?
There was a bobble in your message headers (look for "EST" above); does that count as high visibility? Most likely your message's bobble was because the main 'sendmail' daemon on lecserver.nci.nih.gov started running before its tz tables got patched. (The sendmail submit process on the same host knew the right time zone.) The tz database was fixed in August 2005. Do you happen to know when the patch was propagated to lecserver.nci.nih.gov, and when was its sendmail daemon last restarted? Anyway, if AOL is using long-running sendmail daemons or similar technology, that could explain the problem right there. I just now checked my incoming email's headers. Of the 305 messages being sent to me from the Pacific time zone where the 'Received:' line helpfully says "PST" or "PDT", 70 said "PST". That's an error rate of 23%. But all of the errors can be tracked down to a single email server, kasavah.noc.ucla.edu, which I guess I'll send an error report to now.
