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.
