5 C.F.R. § 838.242 Computing lengths of service.
Title 5 - Administrative Personnel
(a)(1) The smallest unit of time that OPM will calculate in computing a formula in a court order is a month, even where the court order directs OPM to make a more precise calculation. (2) If the court order states a formula using a specified simple or decimal fraction other than twelfth parts of a year, OPM will use the specified number to perform simple mathematical computations. (b) Unused sick leave is counted as “creditable service” on the date of separation for an immediate CSRS annuity; it is not apportioned over the time when earned. Unused sick leave is not countable as “creditable service” in a FERS annuity (except in a CSRS component for an employee who transferred to FERS) or in a deferred CSRS annuity.
