How to use it in code

Sample code which would show a prompt with the number of days and hours between now and the selected datetime:

require("datetimeinput").input().then(result => {
    E.showPrompt(`${result}\n\n${require("time_utils").formatDuration(Math.abs(result-Date.now()))}`, {buttons:{"Ok":true}}).then(function() {
        load();
    });
});

To set the initial value, pass a Date object named datetime, e.g. for today at 9:30 :

    var datetime = new Date();
    datetime.setHours(9, 30);
    require("datetimeinput").input({datetime}).then(...
