IBTrACS Reading does not work

[mandli]

The current functionality to read in an IBTrACS file is failing. It appears to read the file in fine but converting it the times to datetimes appears to fail.

 for d in ds.time:
    t = d.dt
    self.t.append(datetime.datetime(t.year,t.month,t.day,t.hour,t.minute,t.second))

Error:

TypeError: 'DataArray' object cannot be interpreted as an integer
