is there a way to have quarter of a year intervals in the simile timeline javascript widget?

Question

When using the javascript timeline widget simile, i see there is hour, day, week, month, year intervals. Is there anyway to have an interval be a quarter of a year?

i am trying to group events into Quarter1, Q2, Q3, Q4 in 2010.

Answer 1

The Simile wiki has some notes on how to add new intervals to Timeline.DateTime by editing date-time.js and labelers.js. This would be one way to add support for a quarter of a year interval.

Looking at the source code repository for Simile timeline, there is also a planning extension to timeline that includes support for Timeline.PlanningUnit.QUARTER, which may already do what you want
