We determine and analyze the quantum phases and time delays in photoionization and photorecombination of valence 3p and 3s electrons of argon using the Kohn-Sham local-density-functional approach. The time-dependent local-density approximation is used to account for the electron correlation. Resulting attosecond Wigner-Smith time delays show very good agreement with the recent experiment on argon that measured the delay in 3p photorecombination [S. B. Schoun, Phys. Rev. Lett. 112, 153002 (2014)PRLTAO0031-900710.1103/PhysRevLett.112.153002].
