示例1: timezone

def timezone(zone):
    r''' Return a datetime.tzinfo implementation for the given timezone 

    >>> from datetime import datetime, timedelta
    >>> utc = timezone('UTC')
    >>> eastern = timezone('US/Eastern')
    >>> eastern.zone
    'US/Eastern'
    >>> timezone(unicode('US/Eastern')) is eastern
    True
    >>> utc_dt = datetime(2002, 10, 27, 6, 0, 0, tzinfo=utc)
    >>> loc_dt = utc_dt.astimezone(eastern)
    >>> fmt = '%Y-%m-%d %H:%M:%S %Z (%z)'
    >>> loc_dt.strftime(fmt)
    '2002-10-27 01:00:00 EST (-0500)'
    >>> (loc_dt - timedelta(minutes=10)).strftime(fmt)
