Description of problem: The ac command summarizes how much time you spend online, by reading /var/log/wtmp. The '-d' option breaks it down by day. Unfortunately, ac counts simultaneous logins as working twice (or three times) as hard, letting you turn an 8-hour day into a 16 or 24 hour day. The sac command is a similar program, but with a '-c' option which fixes the problem: an 8-hour day is counted as 8 hours, unaffected by how many times you're logged on simultaneously. Version-Release number of selected component (if applicable): psacct-6.3.2-41 How reproducible: All the time Steps to Reproduce: 1. sign on two sessions simultaneously for one hour. 2. ac -d username 3. see your time say 'two hours'. Actual results: You appear to have done two hours of work. Expected results: You should appear to have done one hour. Additional info: The 'sac' command is available at http://mama.indstate.edu/users/ice/sac/ , and rpms for 'sac' are available at http://rpm.pbone.net/index.php3?stat=3&search=sac
FC5 is no longer supported, there will be no further updates released for it.
The version of psacct on Fedora 7 is 6.3.2-44, and it still has this behaviour. The version of psacct on Fedora 8 is 6.3.2-48, and it still has this behaviour. Try harder.
