A few things.

1. "Precision" is probably the wrong word there.  "Resolution" seems 
more correct.

2. If your system returns figures after the decimal point, it probably 
has better resolution than one second (go figure).  Depending on what 
system it is, your best bet to determine why is to check the 
documentation for your system (also go figure), since the details are 
not really handled by Python.  Going by memory, Linux will generally be 
1ms resolution (I might be off by 10 there...), while Windows XP has 
about 64 ticks per second, so .015625 resolution...
