A comment on Debounce in Bash. Parent comment

It's worth noting that OP's example works in any Bourne-compatible shell. I don't think `date +%s` is costly enough to warrant losing the portability.

I wouldn't be worried about the performance cost of using `date +%s` personally, I'd be concerned about what happens when the user or an automated process changes the system time.

For example, what will happen in the debounce function if the user sets the system time backwards by a week after a limit has been set?

Good point, didn't think of that.

The title said bash.

Replace "local" with "typeset" and what I wrote is compatible with KSH too -- not Bourne nor POSIX, I know, but still.
