Simple datetime bucketing and synthesis for correlation analysis.
Uses the single column analysis to deduce a suitable bucket size (not too large, not too noisy).
Generates a sample from the bucket snapped to the next-smaller time interval.
(For example: bucket is an hour wide -> generate random number between 0 and 60 minutes and add these to the hour).
