Maximum Timeout after first step in the Funnel

I’m interested to know what is the maximum timeout after first step (in minutes) in the funnel?

I’ve put now 20160 min (14 full days) and it seems PX is accepting it, but I’d still like to know what’s the max value can go.

Btw, 14 days is how much our free-trial lasts so we want to see if the user went through all of the steps in that period.
