.Dt CLOCK 3
The
.Fn clock
function conforms to
-.St -isoC .
-However,
-.St -susv2
-requires
+.St -isoC
+and
+.St -susv3
+which requires
.Dv CLOCKS_PER_SEC
to be defined as one million.
-.Fx
-does not conform to this requirement;
-changing the value would introduce binary incompatibility
-and one million is still inadequate on modern processors.
