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).
