Hi guys,  
With help and inspiration of @zakraket 's flows to calculate with numeric time, I found a way to convert numeric time to time and vice versa; So we can calculate with time stamps. Maybe it can be of any help.  
(And @RonnyW , your code is impressive, but way out of my league 🙃 )

> Got something wink Flow 1 - Convert departure time to numeric time (To be able to enter the departure time as normal time 00:00 format) . Script: // convertTime2NumericTime.js - Convert time to Numeric time (like: 15:30h -\> 1550) let timeIn = args[0] let timeNumeric = 0; if (timeIn == '' || timeIn == undefined) { console.log ('Missing argument'); return(false); } else { // If the hour is 1 - 9, add a leading 0 so time is formatted as f.i. 09:30 var charCount = Array.from…

The other used flows;  
The usecase is a calculation of:  
when to start charging a car,  
depending of the remaining charge time (reported by the charger, in minutes),  
and the departure time (user entered time).
