The Annenberg Political Fact Check took a look at the available data back in February of 2004, and had this to say.

An additional witness came forward to say that he had seen Bush at the base. John W. “Bill” Calhoun was quoted by the Washington Post and others as saying he saw Bush sign in at the base eight to 10 times for about eight hours each from May to October 1972. However, as previously noted, there is record of Bush being paid for only two days of Guard service during that period, Oct. 28 and 29 1972. A White House spokesman could not offer an explanation for the discrepancy.

Furthermore, the Annenberg reports only that Bush was paid and credited for service - not that he actually did duty.
