<pre>
Whether to use the timecode, as specified in timecode config, when setting:

- `availabilityStartTime` attribute in DASH manifests.
- `#EXT-X-PROGRAM-DATE-TIME` tag in HLS manifests.

If false, ignore the input timecode and use the time from system clock
when the manifest is first generated. This is the default behavior.
