If you are working with multiple timelines on a drawing page, you can synchronize intervals across the timelines so they are always concurrent. For example, if you change the date of the interval on Timeline A, the synchronized interval on Timeline B will automatically be changed in the same way.
Synchronize interval with
Open the drop-down list and select the existing interval that you want the new interval to synchronize with.
Note: You can synchronize intervals only across multiple timelines; you cannot synchronize intervals that are on the same timeline.
Date format
Select the format you want for the synchronized interval. The Example box shows you a preview of the format you've selected.
Can I un-synchronize?
Once two intervals are synchronized, the only way to remove the synchronization is to delete one of the intervals. Select the interval and press the Delete key. Then you can create an un-synchronized interval by dragging an interval shape onto the timeline.
