Sanity check plese (Vista NTFS timestamps)

I'm suffering from brain fade or something at the moment

I have a file which shows MAC times which are near-identical under
File-Properties in Vista
Created : Jan 6 2009 8:09:19 a.m.
Modified : Jan 6 2009 8:09:20 a.m.
Accessed : Jan 6 2009 8:09:20 a.m.

Autopsy2.21 with SK 3.0.1, however gives the following :

Written : 2009-01-05 19:09:20 (PST)
Accessed : 2009-01-05 19:09:20 (PST)
Changed :  2009-01-30 17:24:54 (PST)
Created : 2009-01-06 07:09:19 (PST)

BIOS clock is 12 hours adrift and TZ is set to PST even though the machine
is based in the UK.

Any thoughts on this ?

I don't believe Vista's report completely anyway because I know someone
has "had a look" at the machine without following correct process.

I've just loaded another copy of the case into Autopsy and left out  
the TZ and clock skew data. I now get consistent timestampes for the  
written, accessed and created fields.

On that basis, I think there is a bug somewhere and that the clock  
skew is not being correctly deducted from the Created time, even  
though the timezone adjustment is being applied. Time to get out the  
pencil and paper....

Hi Angus,

I just did a test on an NTFS image here and the "-s" clock skew  
calculation works correctly, so I don't know how to explain what you  
are seeing.  If you still have the image, I would be interested in the  
results from the following:

run 'istat' on the file specifying the clock skew:

istat -s 43200 IMG MFTNUM

and then with clock skew and timezone:

istat -s 43200 -z PST8PDT IMG MFTNUM

Do these look correct?

thanks,
brian
