Feature request: Ability to customize output

[cohml]

Version: 0.3.1

So far as I can tell, the autotime output format is fixed and unmodifiable:

time: <duration> <units> (started: <date> <time> <GMT>)

At a minimum, it would be great to be able to do something like disable the timestamp - I don't need to know my timezone every time I run a command.

As a stretch goal, a nice interface for customizing the individual output components, such as with bold the duration and units, dim the time: / started:, perhaps even add some color, etc. would be wonderful.

As things stand this extension is already super useful, but very barebones. Let me know if no one is available to work on it, and I could perhaps take it on.
