If the ``datetime`` is "naive" (i.e. it has no associated timezone information), it is assumed to be in UTC. These timezone calculations are **not** performed if the value is of type ``datetime.time``, as without date information there's no way to determine what a given time would translate to in a different timezone without information about whether daylight savings time is in effect or not. This means that time values are left as-is, and the value of the `tzinfo` parameter is only used to display the timezone name if needed: >>> t = time(15, 30) >>> format_time(t, format='full', tzinfo=get_timezone('Europe/Paris'), ... locale='fr_FR') u'15:30:00 heure normale d\u2019Europe centrale' >>> format_time(t, format='full', tzinfo=get_timezone('US/Eastern'), ... locale='en_US') u'3:30:00 PM Eastern Standard Time' :param time: the ``time`` or ``datetime`` object; if `None`, the current time in UTC is used :param format: one of "full", "long", "medium", or "short", or a custom date/time pattern :param tzinfo: the time-zone to apply to the time for display :param locale: a `Locale` object or a locale identifier rr)r,r rQrcrr)rrWrrUrrrrs 7   rTcCs<t|}|r$||jvr$t||j}|j|}t||||S)aReturn a time and/or date formatted according to the given pattern.
