How to merge timestamped data

If you want to merge 2 sets of timestamped data, and they have identical timestamps, you can do so using a Join transform. But, if the timestamps don’t exactly match up (e.g. they have different intervals), you can easily merge them using the Interpolate transform. Here is a simple example of merging timestamped solar panel and weather station data.
