ProcessBook: Modify the format of the timestamp

Hi,

I'm a new Pi ProcessBook user and I've a question.

Is there any way to modify the format of the timestemp shown with a value.

Current: 04/25/2013 2:44:24.45631 PM

I'd like to have: 04/25/2013 2:44:24 PM so without the millisecond part. How can I get the same result, just without the .45631.

Thanks a lot.
