Why not add a new function rather than modifying time.time()?
(after all its just a timestamp, does it really need nanosecond precision?)
For those who do want super-accuracy then add a new function
time.picotime() (it could be nanotime but why not future proof it :) )
which returns an int represent the number of picoseconds since the
epoch. ints never loose precision and never overflow.
