:) Time does cause memories to fade. :)

What target might this have been used on powerpc-elf? powerpc-eabi?
libgloss/rs6000 has sim-getrusage.S which this is built upon. Would it
make sense to move it there?

Confusingly, there is reent/timesr.c which calls _times().

All I know is that it is in an architecture specific directory and it is
an OS/libgloss BSP specific file. I just want to find it a new home.
