The $context.event.timestamp variable is an ISO 8601 formatted timestamp and will be in UTC.
So if you’re ultimately passing this to Tasker, it should be able to parse ISO 8601 formats. Or if you’re just displaying the notification directly, you might be able to use the /date endpoint noted in this thread and pass the $context.event.timestamp to the input field.
With the release of Expressions, we would recommend using those directly.
