New Email
Ye That Know,
My local Boy Scout group had a competition in which submissions were emailed to me. The first correct submission was to be the winner.
There were two submissions within 10 seconds of each other !
Question: To what resolution are the times on the email servers set ? Are they literally accurate to the second, or better ?
I ask because most home computers are only accurate to the minute.
Below are some snippets from the email headers:
Notes: These two boys are brothers. Each email came from a separate IP Address so I think each was at a different computer. Both use Yahoo email.
I'd like to decide this on the technical info provided in the email headers.
