Function for converting a long registry value to a date

[MHengst]

I'm pulling the registry key HKEY_LOCAL_MACHINESoftware\Microsoft\Windows NT\CurrentVersion\InstallDate on NT machines and the number contained in that key is something like 958778695. I'm guessing that the number is the number of seconds since whatever the start date was back in 1970 or so. I want to get an actual date out of the thing, i know in C++ there is a function that converts it, is there once for VB or do i need to code my own?
