In the absence of pre-existing uses, seconds make the most sense.

I absolutely agree with this. Most developers will have experience with
jQuery's animate,
or similar, and will therefore expect milliseconds. But whenever I use
milliseconds I always
pull up a calculator and work it out automatically, and I doubt I'm the
only one.

So my vote is for seconds, but to realise people will be expecting
milliseconds.
