think that /bin/time is dividing the number of clock ticks as returned
by the times() system call by 100 rather than 60.
I think that the /bin/time source compiles in the value of HZ from
<sys/param.h>. If the header file is incorrect, then the wrong value
must have been compiled in.
I don't know why csh gets it right. Perhaps it reads HZ from the
environment?
