How to use the googlemaps.convert.time function in googlemaps

:param timestamp: Timestamp specifies the desired time as seconds since
        midnight, January 1, 1970 UTC. The Time Zone API uses the timestamp to
        determine whether or not Daylight Savings should be applied. Times
        before 1970 can be expressed as negative values. Optional. Defaults to
        ``datetime.utcnow()``.
    :type timestamp: int or datetime.datetime
