def get_modified_time(self, path, format='timestamp'):
        """Returns the last modification time of a file or directory.

        How time is returned is determined based on the given `format`
        string as follows. Note that all checks are case-insensitive.
        Returned time is also automatically logged.

        1) If `format` contains the word 'epoch', the time is returned
           in seconds after the UNIX epoch. The return value is always
           an integer.

        2) If `format` contains any of the words 'year', 'month',
           'day', 'hour', 'min' or 'sec', only the selected parts are
           returned. The order of the returned parts is always the one
           in the previous sentence and the order of the words in
           `format` is not significant. The parts are returned as
           zero-padded strings (e.g. May -> '05').

        3) Otherwise, and by default, the time is returned as a
           timestamp string in the format '2006-02-24 15:08:31'.

        Examples (when the modified time of the ${CURDIR} is
        2006-03-29 15:06:21):
