Currently this is the designed behaviour. It shows time converted in minutes and seconds only.
So I believe that the duration is correct in terms of minutes and seconds for your presentation.
We can however consider this as a enhancement request and try to address it in coming releases.

but if the duration exceeds 60 minutes, it will truncate the time value .
moreover , what am I asking about is the total play time of the presentation, is this adobe 's practice that a presentation must not be over 1 hour?

There is no restriction on the Presentation time duration.
If the duration exceeds 60 minutes, it still show the correct duration in terms of Minutes/seconds.
The behavior should be correct in SWF output. This seems a bug in HTML5 output . We will try to fix this in the coming release.
