Welcome to hell.

You can just pass a datetime64 object to pandas.Timestamp:

In [16]: Timestamp(numpy.datetime64('2012-05-01T01:00:00.000000'))
Out[16]: 

I noticed that this doesn't work right though in NumPy 1.6.1:

numpy.datetime64('2012-05-01T01:00:00.000000+0100')

Also, pandas.to_datetime can be used (this is off of the dev version, haven't checked v0.9.1):

In [24]: pandas.to_datetime('2012-05-01T01:00:00.000000+0100')
Out[24]: datetime.datetime(2012, 5, 1, 1, 0, tzinfo=tzoffset(None, 3600))
