Seconds since 1/1/1970 is often called "seconds since the epoch" and
mpl provides a conversion routine for dates in this form
from matplotlib.dates import epoch2num
e = int(mydate) # convert your date to seconds since epoch
d = epoch2num(e) # a mpl datenum
epoch2num also works over arrays or sequences of epochs.
