I have a countup app. Here is the thing: https://stackblitz.com/edit/web-platform-mjepwa?file=main.js]
I have this code in my function. It sets from when the timer starts counting.
past = Date.parse('2023-02-8 02:20:00');
I want to set the timer with "type="datetime-local" input.
I have no idea how to do it. Thanks in advance!
