Fix for issue #619 (closed) - Will not make time source attempt for static streams unless UTC timing in manifest advise to do so.
Partial Fix for issue #601 (closed)
- Avoids using "utc timing sources or date header if SegmentTimeline is present.
- Maintains the same live edge detection steps as 1.4 if not SegmentTimeline.
- Will still use MPD based time sources if present (same functionality as 1.3)
