It returns int, which is year 2038 safe on all systems. Copy and paste
is great, right?

What's the point of this inline? Explanation is missing in
changelog.
Also this wants follow up patches which fix the call sites and remove
that inline helper again.

Changelog is missing that none of the existing hooks is using the ts
argument and therefor the patch is not doing any functional changes.
