Clock input from data

Hello, I am using Grafana 7.1.5.
I installed the clock plugin, and I was able to use it in countdown mode. The problem is that I can’t find a way to enter an end time that is not by typing it on Grafana server UI.
I would like to to put an end time value from the database, mean getting the end time value in real time.
Is there a way to do it?
Thanks for the help.

same question for me … I want to fill the “Countdown -> End Time” field with something like

'SELECT tfinal FROM table where … ;

did you solve the problem ?
