Logically you could do:

>>> import mx.DateTime
>>> mx.DateTime.strptime('2000238','%Y%j')
<DateTime object for '2000-08-25 00:00:00.00' at 403ae410>

However that doesn't work on all systems.  Works on my Linux systems but not
my BSD ones :(  Depends on the C implementation of strptime which has never
been 100%

Probably better to do:

year,day = ...
mx.DateTime.strptime(year,'%Y') + int(day) - 1

eg:

>>> mx.DateTime.strptime('2000','%Y')+237
<DateTime object for '2000-08-25 00:00:00.00' at 4039c138>


which is more portable.
