Ah, drat -- hit the wrong key and sent the last post before I had finished
writing it... the following is what I *intended* to send.

If you look at the function ,time.time() returns time in

This brings me to an even simpler method of getting the resolution of

Starts getting confusing...
on linux I get

Is it mentioned somewhere that print truncates floats ?
Thats new to me. Kinda surprising that is.
print '%.30' % time.time()
xxx.23456678990...
I knew it must have been hiding somewhere
On windows I'd expect a resolution of

'print' prints str(time()). On the interactive prompt, you see
repr(time()). float.__str__ truncates. I don't know where it's
documented, but this is the reason why you see the truncation.

Hello all
I have the problem of how to calculate the resolution of the system
clock.
Its now two days of head sratching and still there is nothing more than
these few lines on my huge white sheet of paper stiring at me. Lame I
know.
import time
t1 = time.time()
while True:
t2 = time.time()
Depends iff you are using Linux, print
cat /proc/cpuinfo
and look for the line cpu ...Hz: Parsing that would be
straightforward.
Keep in mind, the time.time() function reports the wall clock time,
which usually has up to a millisecond resolution, regardless of the CPU
speed.
