Returning earliest date in a dataset with an expression?

Hey y’all,

As always I appreciate any help I can get. I have dataset tags that I need to parse and return the earliest and latest date for. I have searched the forums and haven’t come up with much. Script or expression doesn’t matter.

Times are formated as: 2019-07-17 11:13:19.779

Use the sortDataset function, then return the first row; something like:
sortDataset({}, "timestamp")[0, "timestamp"]

An expression example, for completeness:

minDate({Root Container.Power},'Date Column')

:doh: forgot about minDate entirely.
