-- Option variable: showtime Default value: `false`

When `showtime` is `true`, the computation time and elapsed time is printed with each output expression. The computation time is always recorded, so `time` and `playback` can display the computation time even when `showtime` is `false`.

See also `timer`.

```(%o1)                                true
(%i2) ```
