SRL run times

database related question:

how do you store run times?

issues:

- most runs will be in terms of seconds
- sometimes you will want to break a tie or time your run more accurately, to the frame. this would allow either centiseconds or milliseconds
- if two runs tie at the same second, but one was timed more accurately, we want to assume the untimed one is .999 and loses to the accurate timed run
- sometimes there will be multiple timing methods for a game -- for example "Game Time". Game Time sometimes goes by minutes, sometimes by seconds, and sometimes centiseconds/milliseconds.
- for PC runs you may want to time the run without loads. In this case it would probably always use centiseconds/milliseconds.
- we don't want to do stupid stuff like put 2:31:00 game time for a game that only tracks minutes. We'd rather put 2:31.

now, how do you store the run times in the database?
