Hi! I am looking for somthing similar.
I installed the System Time Plugin () and I want to show a custom countdown.
The User has 3 input fields. One for Days, Hours and Minutes. So if you enter 1 Day, 12 Hours it should display a Countdown counting down the entered amount of time.
But it should work even if you close the app for a while and reopen it a few hours later (thats why you need the plugin).
So if you launch a timer you need to get the current system time (I used the unix format) and then add the entered Amount of time and store it. And every x Seconds (or whenever you want to refresh your countdown timer) it should show the remaining time. Did anyone already create something like this or know a good/easy way to do this?
