Nope - you can't *exclude* a time, you can only include it.

If you're brave, though, you can edit the script and reverse the behavior. If you make a copy of the script and save it to "Alert Condition - Scheduled (reverse logic).ppx" (or something similar), you just have to edit one line of the script to change the behavior.

Line 115 of the script is this:
Code:
      if ((Time < StartTimes(CurDayOfWeek) / (24 * 60))) or (Time >= ((EndTimes(CurDayOfWeek) + 1) / (24 * 60))) then
        ' We're outside the time window!
        exit sub
      end if


If you change it to this, then the time window will be an exclusion window, rather than inclusive:

Code:
      if ((Time >= StartTimes(CurDayOfWeek) / (24 * 60))) and (Time < ((EndTimes(CurDayOfWeek)) / (24 * 60))) then
        ' We're inside the time window - don't check!
        exit sub
      end if
