Do you mean the "timeleft" command in the console?

something in regards to that i think, but it's being spit out automatically ever 10 seconds or so. I tried to set up that advertise plugin to do something like that but i didn't have much luck.

I know in L4D they have a 'wait' command that will automatically execute whatever follows it after the set amount of time. I don't know if that's a thing in TF2.

wait is disabled in almost all servers now. However if you're worried about time left there's now an option with huds to display the server time left. Really good for tracking ubers as this timer doesn't change when points are captured.

Check to see if your hud has it set up by putting "tf_hud_showservertimelimit 1" in console. If it is not Crespi made a really good guide on how you can add it yourself fairly easily.

I have it so that whenever I open up scoreboard it runs the "timeleft" command. Might be a workaround for you.

bind mouse1 "+attack; timeleft"

That isn't a server thing, it's a client thing. He binds tab to include a command that shows how much time is left, as well as the scoreboard. The following is the alias and the bind:

alias +scoreboard "+showscores; timeleft; net_graph 4"
alias -scoreboard "-showscores; net_graph 0"
bind tab +scoreboard

Note: this also includes net_graph, which is pretty useful as well.

ok, that makes sense. thanks guys.
