Sybren A. Stüvel caa2f9ccf1 Shaman: improve logging & checking of timestamps
Add more logging of timestamps in the actual code, and a few sanity
checks in unit tests.

These were useful while trying to find the root cause of #104218 and might
be useful in the future too. The solution to that issue will be committed
later.
