I.E. "this is an option I personally use". Got it.

Huh, digging into it, -atime isn't seconds, it's _days_. There should
probably be -asec and friends too, but I'm reluctant to add new API out
of the blue. (And if I was going to do that I'd want to add a suffix to
-atime to specify seconds, minutes, or hours.)

Ok, how about this: I'll implement the existing -amin/cmin/mmin api but
not add it to the help text, and _also_ implement an "-atime 3m" suffix
to specify units (years days hours minutes). Then _document_ the second
one, but accept both syntaxes for compatibility, and have "-atime" vs
"-amin" change which default units to use.

Sound reasonable?
