Hi. Is there no built-in way of making "sleep" sleep in increments of minutes, hours, etc? The GNU "sleep" can be invoked like "sleep 1h" for an hour. The FreeBSD one's manpage leads me to believe we can only use seconds, which is kind of annoying. Is there an undocmented or missing feature here? Seems really trivial to implement. ~ $ sleep 1h usage: sleep seconds
