aem 6.2 :-Timeline for a page does not have workflow related entries from before 1 month

[anjaliprasad89]

Timeline for a page is listing workflow related activities only if they happened within a month from current date.

It is listing publish/unpublish activities for last 2-3 months and more.

Is there a way to see workflow related logs also for last one year or so

I am unaware of functionality that lets you modify these date values. There is no mention of this in AEM docs.
