At irregular intervals, I dabble in time series analysis. Speaking of irregular intervals, this is a problem with a lot of time series data. Yet many analysis techniques assume regular spacing of the time stamps. Quite some time ago, I developed a prototype component which uses simple interpolation to regularize a time series to a specified interval size. I keep meaning to do more with it, but my day job gets in the way. 

If you'd like to see such a component in Pipeline Pilot and/or other enhanced support for time series data (or series data in general), please upvote. If you have other specific proposals along these lines, please add them in the comments.
