between the six-year statute of limitations contained in section 2501 and the six-year presentment period set forth in section 605(a) of the CDA. However, those two sections are not interchangeable; they serve distinct purposes and are governed by different rules of application. Most important here, the United States Court of Appeals for the Federal Cir cuit and this court have held that the six-year statute of limitations contained in section 2501 does not apply to suits brought under the CDA. See Pathman Constr. Co. v. United States, 817 F.2d 1573, 1580 (Fed.Cir.1987) (“Once a contractor elects to proceed under the [Contract] Disputes Act, the six-year statute of limitations in 28 U.S.C. § 2501 is not applicable.”); Sys. Planning Corp. v. United States, 95 Fed.Cl. 1, 4 (2010) (<HOLDING>). For that reason, the court need not determine
