Soon after 1.5 came out I noticed this bug, too. I posted patches to
fix it. If you can't find them in an archive near you, they are at
ftp.vmars.tuwien.ac.at in file /pub/minix/hp/times.patches.

Times now returns the time in ticks since boot time.

BTW, Andy, did these patches make it into Minix 1.6?
