As I said, for logical time it is the smallest number representable in
Pd. In practice, you would never be able to run something that fast for
long period (say, 1 second) of time, because your CPU most likely
wouldn't be fast enough.

That is what I'm trying to say since - I don't know - at least three

[timer] shows the correct number. However, even that simple patch clogs
my CPU when setting it to 1e-06, which actually means 'send a billion
bangs per second'.
