DateTime structures of choice.

Which datetime-related structures should we be using?

A recent PR by @ctron has

-   published_at: DateTimeUtc,
+   published_at: time::OffsetDateTime,

Is there a tenet here we should spread more widely?

chrono is dead, time 0.3 so the new thing. … time has 231,569,495 downloads, chrono has 155,970,055.

chrono actually depends on time 0.1, adding stuff on top. But time 0.1 having fixed a CVE, didn't get updated in chrono for quite a while. That was around 2021, where many projects moved to time 0.3. Figuring out that projects actually didn't need to "on top" stuff of chrono.

And just for timestamps, I don't think we need it either. Maybe chrono updates to time 0.3 some point. By stick to time 0.1 if we don't need it.

So, we should remove direct usage of chrono?
