I'd like to be able to classify users into cohorts (or apply a custom user profile property).
I'd like these cohorts (or properties) to hold the calculating of TTC at the user level, in days.
Let's say user does Event A on Jan 1, and Event B on Jan 20… I'd like to make a custom property or cohort that is essentially:
DateDiff ( Date of Event B - Date of Event A) = Age
Jan 20 - Jan 1 = 19 days old
