I've tried to RTFM by searching through the Ignition Docs and asking my friend ChurtGerprTee.

Quick and dirty: I am doing a bunch of charting and am wondering if I call `system.tag.queryTagHistory` on a Derived tag, that does not have historize enabled itself, will the function query the Source tag's history and return it?

Thank you and I apologize if I overlooked a low-hanging fruit.
