> Thank you for acknowledging this issue.  As Mr. Harris states, reversing the
> byte order appears to fix the issue for Windows.  I've passed some raw
> time-stamp values from 6 different Windows PCs to an Excel sheet, to compare
> them (attachment).  Re-ordering the bytes clearly works for WIN98 and XP,
> however for Vista and WIN7 the results imply that the byte order is likely the
> same but there is another bug in the MS implementation.  The time-stamps after
> a 0.1 second delay are different by 93 to 109 seconds.
> 
> This means that embedded devices that rely on *Windows XP-sourced* ICMP time-stamp for clock
> synchronization will fail under Vista or WIN7.
