Who Can Call Time?

An interesting situation just occured with a player in the tank pondering a decision. After a good while the dealer decided the game had to move on, so called time on the player.

The player became irate at this and the table exploded into debate over whether the dealer could call time on the player or not.

When the supervisor was called to the table, he explained that the dealer was not allowed to call time on the player in that situation, and the rabble died down.

For the record the raiser in the hand wanted the player to take his time.
