Ethereal-dev: Re: [Ethereal-dev] NetXray / Sniffer Time Codes [Fwd: NetXRay timing base]
Shortly after discovering some timing problems with Ethereal and
NetXray, I tried to verify the timing factors listed. Unfortunately,
the supplied correction factors were still off by about 10 seconds per
day. Calculations yielded a value of 0.8382229. Currently I don't know
much about what it was captured with other than "It was captured on a
Dolch machine running Windows ??" A filtered portion of the capture
file is attached.

the factor appears to always be 0.8382229, which is about 10 sec per day off of
the numbers you have below. not sure i know why but it would get close enough
for any analysis we would want to do
