Hi,
I cannot get the following code to work

import win32com.client
import time

engine = win32com.client .Dispatch("DAO. DBEngine.36")
db=engine.OpenD atabase(r"testd ate2.mdb")
access = db.OpenRecordse t("select * from test")

access.AddNew()
access.Fields(" test").value=ti me.strptime('10 :00AM', '%I:%M%p')
access.Update()

A first step would be to find out what the expected type of the value
attribute is. For that you can put one record into the test table using
Access with the value 10:00AM for the test field and then run

# all code untested

import win32com.client

engine = win32com.client .Dispatch("DAO. DBEngine.36")
db = engine.OpenData base("testdate2 .mdb")
access = db.OpenRecordse t("select * from test")

access.MoveFirs t()
v = access.Fields(" test").value
print type(v), v

If you cannot guess what Access expects from the output of the script, post
it here (in this thread, no need to start yet another one). Don't just
say "didn't work", give tracebacks and the exact code you ran.

Judging from

http://en.wikibooks.org/wiki/JET_Database/Data_types#Dates_and_times

you will see something like

<type 'float'0.416666 666667

If that's correct you can modify your script

def time_to_float(h , m, s):
return (h + m/60.0 + s/3600.0)/24.0

# ...

access.AddNew()
access.Fields(" test").value = time_to_float(1 0, 0, 0)
access.Update()

You should be able to pass a PyTime or datetime.dateti me object.
