`Date and time classes.
Taken from http://www.pythonweb.org (Web Modules).
By default importing this module imports the Python > 2.3 datetime classes.
Otherwise the less powerful and robust lemon ones are used.
This module is really just meant to be the minimum date implementation that
can be got away with to enable lemon to work with Python < 2.3.
Documentation
-------------
See the Python 2.3 datetime module for documentation on the time, date and
datetime classes. WARNING: These versions do not properly check to make sure
the date you specified is valid.
now() returns the current date and time as a datetime object.
isodatetime2tuple(sql), isotime2tuple(sql) and isodate2tuple(sql) take a
standard isoformat string as would be returned from an sql query and return
the appropriate date or time object. WARNING: Parts of seconds are ignored.
calendar.weekday may break for certain old times. Not sure why, but that is
why it was all fixed in Python 2.3.`

isleap(self, year)
  `Return 1 for leap years, 0 for non-leap years.`

test(self)

class datetime

``

`DateTime(year, month=1, day=1, hour=0, minute=0, second=0.0)
Constructs a DateTime instance from the given values.
Assumes that the date is given in the Gregorian calendar
(which it the one used in many countries today).
WARNING: Only very limited error checking is done for this class.
The tuples are filled with the parameters from the last three numbers
in the current time tuple so only use the first six!!
Variable ranges:
MINYEAR 1
MAXYEAT 9999
year MINYEAR-MAXYEAR
month 1-12
day 1-31
hour 0-23
minute 0-59
second 0-59 Apparantly it is possible to have a double leap second in Python.
However, to maintain compatibility with databases, this isn't allowed.
WARNING: Seconds are rounded to two decimal places.
