"connect time" isn't set correctly when clients connect

[efess]

When you use the "status" command, or query a server via qstat - one of the fields returned is "connect time" which, which would indicate how long a client has been connected. In FTE server, this value is incorrect. Sometimes it seems to reflect the time the server was started, in other cases, I can't really tell what the value means. In the following screenshot, I just connected a client under the name of test:

Note - it says I've been connected for 15 hours.

It seems to boil down to the fact cl->connection_started isn't set correctly when the client joins.

In the original quake, this used to be set when a QSocket was created for a client in the network code:
