Indeed there is with the attached path fixing the bug of using PyLong_FromLong 
instead of PyLong_FromLongLong for long long values in getTime() which was 
truncating the returned values. This patch is also checked in.

>>> from PyLucene import Date
>>> from datetime import datetime
>>> d = Date()
>>> d
<Date: Fri Sep 08 14:01:51 PDT 2006>
>>> dt = datetime.utcfromtimestamp(d.getTime() / 1000.0)
>>> str(dt)
>>> '2006-09-08 21:01:51.753000'   # a GMT value: 14:01 PDT is 21:01 GMT

If you want to express the python datetime in a specific timezone as well, you 
can use datetime.fromtimestamp(d.getTime() / 1000.0, tzinfo) as documented 
here: http://www.python.org/doc/2.4.3/lib/datetime-datetime.html#l2h-1887

I hope this helps
