(c)
(1) Notwithstanding section 5545(a) of this title, premium pay for nightwork will not be paid to an employee otherwise subject to such section solely because the employee elects to work credit hours, or elects a time of arrival or departure, at a time of day for which such premium pay is otherwise authorized, except that—
(A) if an employee is on a flexible schedule under which—
(i) the number of hours during which such employee must be present for work, plus
(ii) the number of hours during which such employee may elect to work credit hours or elect the time of arrival at and departure from work,
which occur outside of the nightwork hours designated in or under such section 5545(a) total less than 8 hours, such premium pay shall be paid for those hours which, when combined with such total, do not exceed 8 hours, and

(2) Notwithstanding section 5343(f) of this title, and section 7453(b) of title 38, night differential will not be paid to any employee otherwise subject to either of such sections solely because such employee elects to work credit hours, or elects a time of arrival or departure, at a time of day for which night differential is otherwise authorized, except that such differential shall be paid to an employee on a flexible schedule under this subchapter—
(A) in the case of an employee subject to subsection (f) of such section 5343, for which all or a majority of the hours of such schedule for any day fall between the hours specified in such subsection, or
