(IRC) How do I find out when a user was last seen in a channel?

I use XChat. How do I find out when a user last logged into the channel or was last there?

/!seen [user-nick] didn't work. It said !seen isn't a command. I don't want my query to be visible to others.

How do I do it then?


On networks with NickServ, you can use INFO command. So, if you want to find out when a user 'Jerry' was last online, you can do:

/msg nickserv info Jerry

If they're online, you can whois them, like:

/whois NickName

Hope this helps :)
