Unit test failed with r253

Could verify with latest v8 and pyv8 SVN code, I can't reproduce it on Windows 
and 
Debian/Linux x86.

Looks like a daylight saving time related problem. I've added:
print str(func(now)), str(now.strftime("%a %b %d %Y %H:%M:%S"))
before assertion and got this:

gauss@pmain:~/Projects/pyv8$ date
Вск Апр 11 19:08:05 MSD 2010

Thanks for your feedback, I will study the daylight saving time more detail 
later :)

I have debug the issue on a debian 5, it seems v8 and python use different time 
zone, it is very strange, I need check their code for more detail. :S

import datetime
import PyV8


class Global(PyV8.JSClass):
    def now(self):
        return datetime.datetime.now()

ctx = PyV8.JSContext(Global())  # create another context with the global object
ctx.enter()
javascript_now = ctx.eval("new Date()")
javascript_global_now = ctx.eval("now()")
python_now = datetime.datetime.now()
print("javascript_global_now=%s" % javascript_global_now)
print("javascript_now=%s" % javascript_now)
print("python_now=%s" % python_now)

Outputs three different timezones on MacOSX:
javascript_global_now=2012-07-21 08:20:06.104000
javascript_now=2012-07-21 07:20:06.103000
python_now=2012-07-21 01:20:06.104915

Same here with 

javascript_global_now=2012-08-27 08:15:01.376000
javascript_now=2012-08-27 07:15:01.376000
python_now=2012-08-27 09:15:01.376350

Python now is actually the correct time.
