Notwithstanding subdivision (a) of Section 46010 or any other provision of law, for purposes of calculating days of attendance in order to compute any apportionment of state funding under this code, a pupil enrolled in a regular day class, including opportunity classes and classes conducted in county community schools, for the minimum day that is applicable to that pupil is deemed to be present for the entire schoolday, unless he or she is absent for the entire schoolday. This section does not apply to any pupil whose attendance is required under this code, or under Title 5 of the California Code of Regulations, to be recorded by clock hours.
