High-resolution timers

[Bryan]

Hi All,

I am searching for a platform-agnostic high resolution timer module to use 
in various entropy collection schemes for cryptographic purposes. The 
standard time module is great on my system ( i686 linux ) :

>>> import time
>>> time.time()
1011195116.002301

It gives me microsecond precision, and for that I am grateful. But the 
module documentation warns:

"Note that even though the time is always returned as a floating point 
number, not all systems provide time with a better precision than 1 second."

I understand that the precision of the timer is hardware-dependent... But 
can someone give me an example of a platform on which time.time() has a 
resolution of less than 1 millisecond ?

Thank-you.
