Python 2.2 doesn't have a decend date/time class.
There's a small compatible library from the Python Web Project.

I download the source and extract the datetime.py then
send it to my phone as a pys60 library.
Here's a simple test that works well.
(Taken from Effbot)

   1  
   2  >>> import datetime
   3  >>> now = datetime.datetime(2003, 8, 4, 12, 30, 45)
   4  >>> print now
   5  2003-08-04 12:30:45
   6  >>> print repr(now)
   7  datetime.datetime(2003,8,4,12,30,45)
   8  >>> print type(now)
   9  <type 'instance'>
  10  >>> print now.year, now.month, now.day
  11  2003 8 4
  12  >>> print now.hour, now.minute, now.second
  13  12 30 45

See its documentation here.
One limitation as a library is that you need to use

   1  datetime.datetime(2004,1,1).now() # work for any version

instead of just

   1  datetime.datetime.now() # python 2.3+

update
======
I add 'staticmethod' expression. Now it works fine.

   1  
   2      def now(self=None):
   3          "Return the current date and time as a datetime."
   4          now = t.localtime()
   5          return datetime(now[0],now[1],now[2],now[3],now[4],now[5])
   6      now = staticmethod(now)
