When is a stream entry timestamp created?

It’s based on stream entry is processed. Also, we can override also by passing the timestamp.

me.AddStreamEntry({
	sourceType: undefined /* STRING */,
	values: undefined /* INFOTABLE */,
	location: undefined /* LOCATION */,
	source: undefined /* STRING */,
	tags: undefined /* TAGS */,
	timestamp: new Date()/* DATETIME */
});
