You will need to either incorporate RTC shield if it has to be specific to the date/day.
Also want to create some variables that store the number of successful access requests were made and just check those variables everytime a attempt is made, something as simple as a INT variable that increments to 1 and if variable > 0 then dont allow.
Or as fancy as storing the time in a variable and then do some calculations next attempt to see if its been longer than an hour.
