[Python-Dev] Drop the new time.wallclock() function? (original) (raw)

To quote: "On Unix, return the current processor time as a floating point number expressed in seconds. The precision, and in fact the very definition of the meaning of "processor time", depends on that of the C function of the same name,"

The problem is that it is defined to return "processor time." This is historical baggage that comes from just writing a python wrapper around the unix "clock" function. Of course, "processor time" is quite useless when one is trying to write timeout algorithms or other such things that need to time out in real time, not just cpu cycles. K

Isn't the highest resolution cross platform measure of "wallclock" time spelled "time.clock()"? Its docs say "this is the function to use for benchmarking Python or timing algorithms", and it would be a shame to add and teach a new function rather than improving clock()'s definition.
