You can use the millis() function to measure time and for this example, you can ignore the fact that it can wrap-around back to zero after many days. So you need two things, code for your Spark core and code for a web page…

Using Spark.publish() with Simple JSON Data

Let’s say you have looked at the Getting Started with Spark.publish() tutorial, but you need to send data that needs more processing once it gets to its destination on the web. You have a lot of choices for the data format, but one simple choice is to use JSON, the JavaScript Object Notation which let you send property names and values in an easy to read and easy parse to format.
