If the complaint sets forth dates that appear, in the first instance, to fall outside of the statutory limitations period, then the defendant may move for dismissal under rule 12(b)(6). See Rohner v. Union Pac. R.R. Co., 225 F.2d 272, 273-75 (10th Cir.1955); Gossard v. Gossard, 149 F.2d 111, 113 (10th Cir.1945); Andrew v. Schlumberger Tech.

B: holding that once a plaintiff has pled facts in the complaint indicating that the statute of limitations is a complete or partial bar to an action it is incumbent upon the plaintiff to plead either in the complaint or in amendments to it facts establishing an exception to the affirmative defense
C: holding that complaint need not anticipate statute of limitations which is an affirmative defense
D: holding that plaintiff failed to plead facts sufficient to allege affirmative misconduct on the part of the government
