Convert Hex Value to Date from Binary Reg Key

Hi,

I am trying to get a date value from the registry that is stored in hex in a
binary reg key. The key looks like this.

[HKEY_LOCAL_MACHINE\SOFTWARE\intel\landesk\virusprotect6\currentversion]
"PatternFileDate"=hex:23,02,19,00,00,00,00,00

When I use WMI to query to the binary registry value it returns an array of
bytes that looks like this:

- arrValues {...} Array of Variant
(0) 35 Byte
(1) 2 Byte
(2) 25 Byte
(3) 0 Byte
(4) 0 Byte
(5) 0 Byte
(6) 0 Byte
(7) 0 Byte

What do I do with they array now? How can I get the date from this array?

Thanks,
Rob

Good question. Do you know what date this value actually represents (i.e. is
it displayed in human readable form by the software)? My quess would be Feb
25, 2005 (2005 = 1970 + 35), but without knowing anything else about it that
is only a guess.

Thanks for that, makes more sense now.

The only thing is that the month is one off. The app (symantec AV) displays
that date as 3/25/2005, but we read that as 2/25/2005 I've checked a number
of servers now and the date is always one off.

I have fixed it in my code by just adding 1 to the month each time, but i'd
still liek to know why it's a month out.

Any ideas?

Hi RobT,

As far as I know, this is "normal" for dates. JScript handles them in a
similar way. The JScript docs have some nice examples of date handling.

Yeah, odd that it is out by a month, but not by a day or a year. Looks like
the month is given as a number from 0 to 11. Why Symantec decided that, I'll
never know. If it is some sort of standard, I still don't know, but will
just have to bow to the inevitable.
