Do we have any metrics on when the most active user activity is across Lemmy / PieFed?

To be clear, the time probably needs to be expressed via UTC / GMT or other time zone labels.

I regularly post across ~half a dozen communities, the most frequent being to my own, where I post at 9AM (UTC-4 / EST zone) so as to hit early risers in the States and afternoon surfers in Europe. But with other posts, I get the sense that it would be better to post later in the day to hit more viewers. I'm just not sure when that would be.

TBC, I usually use the PieFed scheduler to post, so it's no problem for me posting at any time of the day.

Thanks for any insight!
