You would need to have your code check the time and decide whether or not to
run the query. I can think of 2 different ways to do this. First, you
could just build a condition in your SQL WHERE clause to check the system
time to see if it's appropriate. This way would be a bit slower because it
would actually have to connect to mysql and execute the statement whether it
updates or not. The other way would be to put your query in a php condition
block and use the php date function.

Yes, this is true. If it were not then you would have users with the same
session which would be amusing. A session ID is unique though eventually it
will be reused I believe.
Hope that helps.
