Comment 2 for bug 405707

As I said, how do you define who is the *current user* ?
The only info one can gather inside conky, is the login time for the tty connected to conky's standard input. The attached patch adds support for it (it should work on any posix compliant *nix), note that in coherence with the definition, the variable is called conky_user_time (for a single user stand-alone machine used as a desktop this would be the "current" user time).
