I know.  But you brought it up; I responded.

Make can't help it if your tools are broken.  You can either only use
tools that support sub-second timestamps, or you can use only tools that
_don't_ support it, or you can use make's .LOW_RESOLUTION_TIME special
target to tell make about it.  See the GNU make manual.
