Absence Management balances update in arrears. For monthly employees, time taken in one month are transitioned to UCPath the following month and appear on their paycheck the month following. For example, for a leave taken in April, those hours will flow from CalTime to UCPath in early May, then appear on the employee's paycheck in June. If you search for accrual balances after the hours have moved into UCPath, they will update April hours because that's when the leave was actually taken.
CalTime will generally have more accurate leave balances hours because of the interface time. For biweekly employees, accrual balances update on the quadricycle as outlined in the Payroll Processing Schedule.
