I switched over to zsh a few months back and picked up something like this method: https://gist.github.com/zulhfreelancer/9c410cad5efa9c5f7c74c.... This is nice to see for bash and I definitely agree on the usefulness notes, it’s been a nice improvement / helped me not get confused a few times

Isn't that printing the time the prompt was printed (the time the previous command finished)?

This is printing the time you pressed Enter (the time the command started), which is harder and less common, since that's not when the prompt is printed.

This is one way you could do something similar in zsh: https://stackoverflow.com/a/17915260/102182

It looks like zsh can handle updating the time in the prompt quite simply and elegantly.

Yes, I find that solution much simpler.

It keeps the clock up-to-date, but I use Konsole's "monitor for activity" feature, which changes the colour of inactive tabs if there is output.

Instead, this seems to work:

  TRAPDEBUG() {
    case "$WIDGET" in
      zle-line-finish)
        zle reset-prompt
        ;;
      *)
        ;;
    esac
  }

(I don't know if further cases will be required.)

This updates the prompt after "enter" is pressed, but before the command is executed.
