Hi Joe,
Really?
In the Usenet headers of your message is this line:
>NNTP-Posting-Date: Tue, 30 Aug 2005 20:28:41 +0000 (UTC)
This denotes the time you decided to hit the "send" button (or whatever
it's called in your software) and publish your message to the Usenet.
Please tell me the start and stop time of posting this message?
On my desk is a letter. The poststamp on the envelope is stamped by the
Dutch postal service. This stamp includes a date: "22 VIII 05". Please
don't tell me that this means that they started stamping it on midnight
and took a full 24 hours before the stamping was done.
Think about tracking when a web advertisement was served. The NNTP
protocol can't track how long I look at the ad. (IIRC, it's even
impossible to track if I have an ad blocker active). All web advertising
contracts are based on how often the ad is served. What is the start and
stop time of serving an ad?
How about police work? An officer is checking the streets, and at 11:47
AM he sees you driving through a red light. What's the start and stop
times of that? Or if you are caught speeding? Sure, you started speeding
before the officer caught you, and you might have continued after that,
but there's no way that the dept of Justice will ever find out - but
they do know the exact time that an officer of the law saw on his
equipment that you were driving 7.3 mph too fast.
Need I go on, or do you now have enough examples to know that in the
real world, time does NOT always have start and stsop time.
Best, Hugo
