A command line utility, a bit like
[](https://joeyh.name/code/moreutils/), to prepend timestamp

processes where you'd like a historical record of what's taking so long.
Piping anything to `gnomon` will prepend a timestamp to each line, indicating
how long that line was the last line in the buffer--that is, how long it took
the next line to appear. By default, `gnomon` will display the seconds elapsed
between each line, but that is configurable.

You can also use the `--high` and/or `--medium` options to specify a length
threshold in seconds, over which `gnomon` will highlight the timestamp in red
or yellow. And you can do a few other things, too.
If the realtime timestamp updating is distracting or incompatible with your
terminal, it can be disabled:
