How to Reproduce: go to /rhn/Login (or type the url above) and sign in. go to Your Account. Notice that the last signed in date is incorrect.
There were two issues here. One: /rhn/Login never updated the last_signed_in date. Two: The users list page was displaying the wrong minutes, in fact it used the month as the minutes. (ex. if a user logged in last on June twenty-first at 9:35:07 you would see the string, 6/21/05 9:06:07 AM EDT. June is the sixth month and therefore the minutes display six instead of the correct thirty-five).
