time.clock() or time.time()

[peterbe at gmail.com]

What's the difference between time.clock() and time.time()
(and please don't say clock() is the CPU clock and time() is the actual
time because that doesn't help me at all :)

I'm trying to benchmark some function calls for Zope project and when I
use t0=time.clock(); foo(); print time.clock()-t0
I get much smaller values than when I use time.clock() (most of them
0.0 but some 0.01)
When I use time.time() I get values like 0.0133562088013,
0.00669002532959 etc.
To me it looks like time.time() gives a better measure (at least from a
statistical practical point of view).
