            Bug ID: 25542
           Summary: [WebVTT] allowed format(s) for a WebVTT timestamp
           Product: TextTracks CG
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebVTT
          Assignee: dave.null@w3.org
          Reporter: jronallo@gmail.com

Based on the description of a WebVTT timestamp here
http://dev.w3.org/html5/webvtt/#dfn-webvtt-timestamp
I considered that all of the following ought to be valid timestamps for use in
WebVTT cue timings:

00:22.000
22.000
10:34.000
634.000

I filed a issue against mozilla/vtt.js that it was not properly parsing WebVTT
timestamp representing a time in seconds and fractions of a second here:
https://github.com/mozilla/vtt.js/issues/323

They have suggested that this might be a bug in this portion of the spec which
doesn't seem to allow for parsing a "WebVTT timestamp representing a time in
seconds and fractions of a second" like "634.000".
http://dev.w3.org/html5/webvtt/#dfn-collect-a-webvtt-timestamp

Are timestamps in the form of 634.000 (for 634 seconds) valid or is there a bug
somewhere in the spec with regards to this?
