freitasm: After talking to Nate today I have extended the edit window to 15 minutes.
I'd like to ask people to discuss this item HERE, and not drop off topic comments in other discussions. That doesn't help at all. Talking to you ragnor and grant_k ;-)
Oops, I just saw this post now, 5 days later...
Sorry, frustration got the better of me the other day. Twice I edited my post at the 7- and 8-minute mark. Each time the EDIT button appeared, but when I saved the edited version, it was not posted. And yet, I have managed to successfully edit my post on other occasions. Strange...
Hopefully, the 15-minute window will help in this regard. I will wait 5 minutes and try editing this post, to see how it goes.
EDIT: I just noticed that my Timezone has been updated this morning, without me needing to do it. I guess your SQL script mentioned above took care of it. That is very nice -- thank you BDFL.
