I'd also allow for the possibility of just a random accidental finger twitch/mouse click while you were rolling the mouse pointer across the screen, that just happened to be the block link for David.
I accidentally click links all the time, and have, in fact, accidentally blocked people this way before.
I've done the same thing, quite frequently. The first time it happened I was a bit nonplused, but now I just go back and unblock. No big.
ita, if you're having difficulty getting a response from the ISP, I can install an updated time zone file on the server.
Can you bump the time manually for now?
I'd rather just update the TZ file, since it's still going to say "PST" in the date strings.
OK, I'm going to restart httpd...
I'm not sure I fixed everything, though. It might revert back.
