Problem with pywintypes.Time

[Dave Foster]

I am having problems calling a COM method which takes a DATE type as
an argument. I cannot seem to directly construct a pywintypes.Time
instance and pass as an argument.


To illustrate, I created a DLL server, build on VC++ 6 using the ATL
wizard, and added a couple of simple methods, which just return their
arguments.
---------------------------------------------
STDMETHODIMP CPyDateTest::Test1(long code, DATE *date)
{
	*date = (DATE)code;
	return S_OK;
}
STDMETHODIMP CPyDateTest::Test2(DATE date, long *code)
{
	*code = (long)date;
	return S_OK;
}

constructed the COM wrapper using makepy, and I have a test script 

--------------------------------
import win32com.client
import pywintypes
import time

dateProblem = win32com.client.Dispatch('PyDateProblem.PyDateTest')

date = dateProblem.Test1(30000) # construct date via server
print 'Server constructed Date   -----', date
code = dateProblem.Test2(date) # this works fine 
print 'COM Date code             -----', code

date2 = pywintypes.Time(time.time()) # directly construct date 
print 'Directly constructed date -----', date2 
code2 = dateProblem.Test2(date2) # this raises SystemError
print 'Do NOT See this', code2
---------------------------------

when I run this, Python 2.2.2, the date returned from call to the
Test1 method works fine, the directly constructed date raises a
SystemError.
The output I see is, 

-----------------------------------------
Server constructed Date   ----- <PyTime:18/02/1982 00:00:00>
COM Date code             ----- 30000
Directly constructed date ----- <PyTime:03/06/2003 13:14:34>
Traceback (most recent call last):
  File "testScript.py", line 14, in ?
    code2 = dateProblem.Test2(date2) # this raises SystemError

SystemError: NULL result without error in PyObject_Call

Thanking all in advance for any advice or tips on what I am doing
wrong.
