Misa 3d674a6550 Rename time to time_
This is needed for the next step. I want to put all the loop stuff in
their own functions so the code isn't one huge blob, but to do that I'll
need to make 'time' a global variable, but I can't do that because
actually 'time' is already a function, apparently, and you're only
allowed to shadow variables when already inside a function.
