When you manually trigger a page view on click, it doesn’t have a specific time span, it’s just a click. However it still reports significant timespans, sometimes even above a minute. I imagine the timer starts on click, but when does it end?
Oh maybe you found a bug, we forgot to test this use case. Can you pelase create a ticket at: dev.piwik.org and add a HTML snippet showcasing the bug / how to reproduce? we will then fix it
