Although it is possible to evaluate the time elapsed since some other property has changed or to take action based on the time difference between now and another property. It is not possible or practical to have a specific property that periodically updates the elapsed time since in terms of hours or days.
Example.
Last Activity Date shows the last time an activity was updated on a ticket.
Elapsed time since last activity would show the hours/days since the ticket was last updated.
This could be accomplished by
HubSpot creating and or exposing that property
Adding the ability to create a time specific calculated property that is based on the difference between Now and the time based property that you are comparing it to.
Example
Elapsed Time Since Last Activity
Calculation: Time between
Now() current time - Last Activity Date
Possibly add in the option to express this in HH or DD.
My use case is that I want to create a series of thresholds for reporting and taking action. Tracking activity based on the number of days that have elapsed since last activity date. Examples.
No activity
< 7 days
7-14 days
>14 days
Today I create 4 different workflows to update a single property that I call ActivityTracker to track the elapsed time. If I want to be more granular than this, then I am more of less forced to increase the number of workflows that I create to add create or update a viewable elapsed time property.
This same logic can be applied to any `last....date` property.
The same logic can be applied to `created date` vs. now or Age of ticket.
