Cell Duration

 You can set the cell duration in minutes using CellDuration property (the scale property must be set to CellDuration).

Common values:

• 1 (1 minute)
• 15 (15 minutes)
• 20 (20 minutes)
• 30 (30 minutes)

Scale

Use scale for bigger units, such as an hour, day, week, month and year. The scale units are aligned properly (e.g. week starts on the predefined day of week). CellDuration values are always added to StartDate.

You can also create the timeline manually.
