8.     The date of commission will be the date on which a candidate reports for duty. The date of grant of commission will be notified in the Gazette of India. From this date the officer's commissioned service for the purpose of increments of pay, promotion and seniority will be calculated. If, however, an officer is granted an antedate of commission , his seniority for increments of pay and promotion will count from the earlier date. The period of antedate will neither count for gratuity nor will it carry back
pay in any case.
