future is coming too soon

I'd like to suggest that make have a little slop in its concept of the
future.  Consider this message:

make[6]: *** Warning: File `foo' has modification time in the future
(2001-01-18 06:14:24.617133 > 2001-01-18 06:14:24.594368234)

That is what, a whole huge fiftieth of a second off!  I think it's wrong
to expect perfection.  In this case, the filesystem is on a netapp,
which does support ntp -- but its ntp implementation has a tolerance of
.05 seconds, and this is not changeable (as far as I know).  Because of
make's insistence, I've had to turn ntp off and go back to just syncing
the clock via rdate every few minutes.

I looked at the code in remake.c that generates the message, it would
seem you could just have a default adjustment of, say, a tenth of second
or something?
