I recently found, for example, tar sometimes doesn't restore file
mtime correctly (see example below).  But if I mount with -o -2, then
timestamp is restored correctly.  Does anyone rest have similar
experience?  Or am I missing something?

The nfs server and client are both NetBSD/i386 1.2_BETA, but things
are same with FreeBSD-current machine I have.
