Hello.

I would like to calculate the duration of the time filter, (end time - start time) then convert to seconds.

So, if:

1. 15 minutes, seconds is 900
2. 1 hour, seconds is 3600
3. if relative of absolute, then take (end time - start time) and convert to seconds

I would like to then use the duration in seconds in a visualization.

Hello,

So you can use scripted field on your field to display what you would like.

Here is an example for hour of the day.
