To be fair it does slightly more than that (relative times, absolute times, etc) but it is somewhat ironic considering that it advertises itself as an alternative to one liners like "sleep 4231; beep".

You can do sleep 15m; beep

One of the reasons to use this is to avoid beep, which may not even be enabled on your machine.

Use echo '\a' that's what this program uses anyway... It's literally sleep $1; echo '\a' or you can use at if you want exact time.
