Working with last comment time?

In what way does it not work properly?

@W01F,
Following up, Joachim was quick to respond. As far as we know there is no known limitation with last comment time. In what way are you using it and what results are you getting? What where you expecting? If we can reproduce what you are seeing we may be able to help.

Joachim was very fast, and thank you as well for following up. I honestly can't remember the use case or which site I was probably late-night working on for this. We can close as working as expected or however you'd like until/unless I stumble upon it again. Thank you both again for the quick engagement.
