dateutil.parser.parse unexpected and wrong parse

We just had an application where dates were specified as DOY (%j in strptime), dateutil.parser.parse happily parsed this in an odd and incorrect way.

Here is an example
In [5]: dateutil.parser.parse('2013:045 00:00:00')
Out[5]: datetime.datetime(2012, 3, 13, 0, 0)

Instead of failing or doing anything I can figure from the above it gave todays datetime.

It should instead give an error or
datetime.datetime(2013, 2, 14, 0, 0)
