I did not try that but I got it working now in xcode simulator. This function below works fine in Android but not in iPhone (Tracking-page):
const MyDate = new Date(timestamp + " UTC"); this.itemTimestamp = MyDate .toLocaleString();
In iPhone it gives INVALID DATE error.
I see the specification here: https://www.elliotjreed.com/blog/2019-03-20/invalid-date-format-in-javascript-on-ios-devices
But Appery says: "The Date type value is a string which contains a UTC timestamp stored in ISO 8601 format with millisecond precision: YYYY-MM-DDThh:mm:ss.mmm."(https://docs.appery.io/reference/database-api-data-types#date) I don't know if this is the issue in the platform or in the code of mine.. So what is the correct format for that platform with or w/o "Z" at the end?
