Description
Tried with latest master (434f49266749cad6f074920fb61ad3ec6ef90bea) as well as the version in lts-20.23:
When inserting 00:56:03.917384676344, I get out 00:56:03.
This is a regression and I'm surprised that this wasn't caught by tests.
This means I cannot upgrade from LTS 19 (nixos-22.11) to LTS 20 (nixos-23.05).

Research direction
Start by reproducing the reported TimeOfDay roundtrip through SQLite on latest master and the lts-20.23 version. Trace the persistence path for the value and compare the stored and retrieved precision. Done means fractional seconds such as 00:56:03.917384676344 survive the roundtrip, with a regression test covering the case.
