Timer for an obstacle course map

Heya,

I am wondering if a server plugin would be needed for keeping and displaying individual timers for each player on a map or if I can use the entities available in Hammer.

I know I can make a team_round_timer count up, so I could have it triggered at the map starting area and it would display on the HUD for all players. Players would have to keep track of their own starting time and end time this way.

Is there a way to have an individual timer that counts up display for each player (only visible by the player that triggered it) via game_text_tf or something similar?

Thanks!
