Time stamp doesn't seem to be correct in Jupyter notebook magic at least

[psychemedia]

In a Jupyter notebook at least, the time stamp doesn't seem to follow the actual time a function is called?

eg

import time snoop birdseye

# Do not spy on this function
def slow(t):
    a = t
    for i in range(t):
        time.sleep(i*10)

@spy
def foo6():
    for i in range(3):
        slow(i)
