cheap equivalent of now()

[Christian S]

I was waiting for others' comments, but as they lacked, here goes.

First of, do you really have a problem with too many gettimeofday() syscalls
from your
erlang program, or is it just a premature guess of a bottleneck in some code
you
will write? I suggest you go with erlang:now() and see.

If your guess would indeed be true, then you could look at the 'timer'
module. There
are some functions there that could be interesting for 'driving' a timer you
keep in a
process.
