Calculating days since last visit

[Dan_N]

Good day everyone.  I wonder if anyone has a formula for calculating "Days since last visit" out of clickstream data?  I did not see a calculation of this sort in either the documentation or the community.  Thank you.

This is not metrics. This is dimension. The number of days between a visitor's current visit and their most recent visit. This can help you understand visitor behavior after visiting the site.

In clickstream data you should have the field last_hit_time_gmt, this is the timestamp of the prior hit... 

So on the first hit in a session (visit_page_num), you should be able to take this, and the timestamp of that hit to calculate the number of Days since the last visit.
