Exception when printing raw.info

[aweinstein]

Printing the info attribute of a raw object, using 5fac33d, throws the following exception:

Traceback (most recent call last):
  File "eeg.py", line 361, in <module>
    print(raw.info)
  File "/home/ajw/.local/mne-python/mne/io/meas_info.py", line 410, in __repr__
    entr = _stamp_to_dt(v).strftime('%Y-%m-%d %H:%M:%S') + ' GMT'
  File "/home/ajw/.local/mne-python/mne/io/meas_info.py", line 64, in _stamp_to_dt
    datetime.timedelta(0, 0, stamp[1]))  # day, sec, μs
IndexError: list index out of range

I can print the info if I go back to 0c0b8de2. I think the commit that causes the problem is e6fd505ef4e35089ab0b31d69fe371028c79cd53 (but I can't go back to that commit).

This is the info value:

In case it matters, the original data is from a BDF file.

Can you import pdb; pdb.pm() to find out what the info entry is that is causing the problem? It's probably some malformed timestamp that we can make a fix for.

(It was easier to make a PR than to figure it out this pdb business).

I think the problem is that BSD don't have microsecond information in the time of "Start time of recording" field (see this).

PR #4672 seems to fix the problem.
