You can use the VisiblePeriodStart, VisiblePeriodEnd, PeriodStart and PeriodEnd
properties of RadTimeline.
The PeriodStart/End allows you to define the minimum and maximum date available in the control.
The VisiblePeriodStart/End allows you to define what portion of the timeline should be displayed. In other words it could be said that you can control the zooming level.
Note that in order to display the different time units you will need to define different intervals for the hours, minutes, seconds, etc. Those are defined in the Intervals collection
of the control.
You can try those properties and let me know how it goes.
