How to convert a binary time format? Please help

[sdkfz250]

Hi,

I am using the following code to extract registy values from my WM5 mobile phone:

*****************
k$ = Reg_OpenKey(HKEY_CURRENT_USER, "\\System\\State\\Appointments\\HomeScreen");
Reg_GetValues(k$, &Value$);
goto(Value$, 4);
showmessage(Reg_GetKeyValue(k$, Value$, FALSE));
Reg_CloseKey(k$);
******************

The value I want to read is a appointment end time in binary format :00 40 2f 8D e1 27 cb 01

When I run the code the following value is displayed: 728422400

Can anyone help in getting the correct time out of this number?

Thanks in advance

Michael
