Question about data analysis

Does Julia have a Pkg or methods that can process temporal data and extract relevant features?

What is a relevant feature very much depends on the task at hand. What problems are you trying to solve?

hello,i want to solve the question about Power system operation mode clustering,Now I have hourly data,but I want to do it in days,This requires processing of temporal data.

That is still a very vague description, but you may have a look at the following packages.
