That's a good point... and I'm not sure how to handle that. The problem is that the date output is dependent on the locale, and needs to be in a format that can be converted to a unix timestamp (to be consistent with the output of psutil.get_users()). Is there a more readily available setting for the locale that could accomplish this? An output that includes the timezone would be even better, as then dateutil could be used to convert to a timestamp.
