Another Simple Datetime+struct_time Class

        I had shown how datetime can be used in python 2.2
in a <a href=http://www.bigbold.com/snippets/posts/show/1614>previous snippet</a>. Still, it's sometimes too big.

Here's a minimal implementation. It works like both
datetime and stuct_time (as returned by localtime() and gmtime()).

import time

class datetime(object):
    def __init__(self, *argv):
        self.t = time.struct_time(argv+(0,)*(9-len(argv)))    # append to length 9 
    def __getattr__(self, name):
        try:
            i = ['year', 'month', 'day', 'hour', 'minute', 'second', 'weekday'].index(name)
            return self.t[i]
        except:
            return getattr(self.t, name)
    def __len__(self): return len(self.t)
    def __getitem__(self, key): return self.t[key]
    def __repr__(self): return repr(self.t)
    def now(self=None):
        return datetime(*time.localtime())
    now = staticmethod(now)
    def strftime(self, fmt="%Y-%m-%d %H:%M:%S"):
        return time.strftime(fmt, self.t)

Here's its usage

# here it works like datetime.datetime()
>>> t = datetime.now()
>>> t.year, t.month, t.day
(2006, 3, 13)
>>> t.hour, t.minute, t.second
(23, 3, 28)

# but also works like localtime()
>>> t
(2006, 3, 13, 23, 3, 28, 0, 72, -1)
>>> t.tm_year, t[0]
(2006, 2006)
>>> mktime(t)
1142265808.0

# good default for strftime (= ctime)
>>> t.strftime()
'2006-03-13 23:03:28'
