ORDER AND JUDGMENT *

After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.

In this direct criminal appeal, James Walker seeks only credit against his federal sentence for time served in federal custody prior to his conviction. 18 U.S.C. § 3585(b) provides, among other things, credit against a sentence “for any time ... spent in official detention prior to the date the sentence commences ... that has not been credited against another sentence.” Nonetheless, under § 3585(b), “it is the *188 Attorney General who computes the amount of the credit after the defendant begins his sentence.” United States v. Wilson, 503 U.S. 329, 333, 112 S.Ct. 1351, 117 L.Ed.2d 593 (1992). The district court is not authorized to award this credit at sentencing. See id.; see also United States v. Jenkins, 38 F.3d 1143, 1144 (10th Cir. 1994). The judgment of the United States District Court for the District of Colorado is, therefore, AFFIRMED.
