PlayIt Live's clock scheduler is designed to work with full-hour increments only, but you can effectively create shows that start at 30-minute intervals by using Fixed Time Markers within a single clock structure.

Creating a 30-minute clock structure:

Go to Manage > Clocks and create a single clock that contains both half-hour segments. Structure your clock as follows:

1. Add a Fixed Time Marker at 00:00 (start of hour)
2. Add all content for your first 30-minute segment (tracks, voice tracks, jingles, etc.)
3. Add another Fixed Time Marker at 30:00 (30 minutes past the hour)
4. Add all content for your second 30-minute segment

How Fixed Time Markers ensure precise timing:

The Fixed Time Markers act as anchor points that guarantee each segment begins exactly at the specified time. The first marker ensures content starts precisely at the top of the hour, whilst the second marker ensures the second segment begins exactly at 30 minutes past, regardless of how the first segment's content runs.

Scheduling your 30-minute shows:

Once you've created your dual-segment clock, schedule it normally via Manage > Clock Schedule. The clock will be scheduled for the full hour, but the Fixed Time Markers will automatically separate it into two distinct 30-minute segments during playout.

Using different content for each segment:

This approach allows you to run completely different programmes within the same scheduled hour. For example, you could have a music show from 00:00-00:30 and a news programme from 00:30-01:00, all within a single clock structure.

Alternative for different shows:

If you need to run entirely different shows that happen to start at 30-minute intervals, create separate clocks for each segment and use the Fixed Time Marker method to ensure they begin at the correct times within their scheduled hours.
