[DUG] Reading binary data as date/time from registry

[Jan Bakuwel]

Hi,

I'm struggling to find a good reference how I can read a date/time that
is stored in the registry. Its stored in the registry by a Microsoft
product; I'd like to read it with Delphi.

Here are some examples:

DateLastChecked     REG_BINARY    95 a2 58 f2 2d f2 ca 01

When I write dates with Delphi (TRegistry.WriteDateTime(Now()), I get
the following results:

13 may 2010 12:56pm        03 ce dc 3f f1 ae e3 40
13 may 2010 12:57pm        39 75 33 48 f1 ae e3 40
13 may 2010 1:01pm          3e 47 d1 60 f1 ae e3 40

The last 4 bytes seem to resemble the date, the first the time.

When I use TRegistry.ReadDateTime on those entries, I get 30/12/1899.

Suggestions are very welcome!

thanks,
Jan
