MergeDataStreamBased on Time Value

I am using a sensor that Measures Weight at a unpredictable time interval. It records the number of seconds passed from the "start" and the given weight.

I would like to merge this data tree with my another set of Data that is a record of seconds passed since the start... there is a new entry every 1-3 seconds.

In other words, I would like to  Merge a WeightValue with My Main Time Data when the Weight Sensor Time Matches the Main Time... (or round Down if the Time isn't an exact Match)

I have been messing with the Similarity component in order to create a booleanPattern for Dispatch, but I am having difficulty with cross referencing values.

This doesn't feel like a clear description of my problem, but  it is a start.

Anybody that wants to look at the File or give suggestions is very appreciated.

Thanks for any advice.
