Here's how I get monotonic time in Python 2.7:

Install the monotonic package:

pip install monotonic

Then in Python:

import monotonic; mtime = monotonic.time.time #now mtime() can be used in place of time.time()

t0 = mtime()
#...do something
elapsed = mtime()-t0 #gives correct elapsed time, even if system clock changed.
