leap seconds

I am writing a python program to log variable observations.  I have a function 
in the program that computes the current Julian date (or any Julian date 
given date/GMT).  I tested it against XEphem and I was a little off.  I got 
better day/year values for earth (23.9344 and 365.2422) and it got very 
close, but was always 13 seconds off.  Then I checked for the current leap 
second status and it happens to be 13.  So now the program reports the 
correct Julian Date, but my question is:

Do we take the leap seconds into account or not?  Apparently my Linux box 
running ntp, with Python2.2's time module has no idea that they exist.  Can 
someone enlighten me?

Thanks,

Mike
