Re: Error in PyDev but not in the standard python interpreter

Well, it 'appears' to be the same type, but given that the File from one is
different from the other, I think they aren't...

Googling a bit, I found the source:
https://code.google.com/p/netcdf4-python/source/browse/trunk/netcdftime.py?r=1117
and it has a 'datetime' which says: "Phony datetime object which mimics the
python datetime object", now, I'm not sure why it works in the Python shell
but not in the IPython shell integrated in PyDev... You may want to create
a module and do a debug run to step into the 'num2date' call to see what
differs there... (i.e.: I think that if you do isinstance(d1, datetime)
it'll return false, as it seems to be a netcdftime.datetime object).

Best Regards,

Fabio
