http://uptime.netcraft.com states:

Operating systems we can usually work out uptimes for are:

     * BSD/OS
     * FreeBSD [but not the default configuration in versions 3 to 4.3]
     * HP-UX [recent versions]
     * IRIX
     * Linux on Intel x86 processor, kernel versions 2.1 to 2.5.24
     * Linux on ARM, M68k, MIPS, PowerPC, S/390, SH and SPARC processors
     * NetApp NetCache
     * Solaris 2.6 and later
     * Windows 2000
     * Windows Server 2003
     * Windows XP

Operating systems that do not provide uptime information include;

     * AIX
     * AS/400
     * Compaq Tru64
     * DG/UX
     * Linux before kernel version 2.1
     * Linux on Alpha and IA64 processors
     * Linux on Intel x86 processor from kernel version 2.5.25 (see below)
     * MacOS
     * MacOSX
     * NT3/Windows 95
     * NT4/Windows 98
     * NetBSD/OpenBSD
     * NetWare
     * OS/2
     * OS/390
     * SCO UNIX
     * SunOS 4
     * VM


Is there some reason:

1)  they can't collect uptime from NetBSD?

and

2) they can't seem to distinguish between NetBSD and Open BSD?
