I needed some kind of low-level system counter to implement a clock() built-in while writing the interpreter in Crafting Interpreters and common-dylan:timers has almost the right thing and seems a natural place to add one.

This doesn't feel right yet. I think a timer should use nanoseconds. I could truncate the seconds to some arbitrary time in the past that would fit in a single integer, maybe? But it's not that important so I'm just closing this. |
