I would like to set the color of the field to green if it is younger than 1 week. The Time Format is Like this ('2023-04-19 08:57:10'), yes the format is with the apostrophe. First I tried at the UI just a Range color definition, but it doesn't work i think it's bcs of the apostrophe.
In order to do calculations and numeric comparisons, you need to parse the string into epoch format using strptime()
