Hmm, now that you talk about it, I think we need to look at this more carefully. We need a way to set/get the time system used, and to set/get the current time left for a given player. So maybe: set_clock_type <time system> <parameters> set_clock <color> <time left in this period> <parameters> get_clock_type get_clock <color> Here "get_clock" returns exactly the same as "set_clock_type", and the format of "get_clock" returns exactly the same as "set_clock". Then we can specify:

absolute: *et_clock_type parameters: <time per player> *et_clock parameters: <time left for this player>

canadian: *et_clock_type parameters: <main time> <byoyomi time> <byoyomi stones> *et_clock parameters: <time left in this period> <stones left in this period or 0 if we are in main time still>

japanese: *et_clock_type_parameters: <main time> <byoyomi time> <# of byoyomi periods> *et_clock parameters: <time left in this period> <byo-yomi period, or 0 if we are still in main time>

etc...how's that?

However, it is useful to have byo yomi in gtp to interface programs with IGS or NNGS, and with graphical front ends.. I agree that we should let room for any time system to be supported. In the get_clock command, how do we know if we are in byo yomi or in the main time, and how do we know there is no byo yomi ?
