db fetch time claims to take zero seconds

```
Fetching state from DB for room '!redacted:t2l.io'...
[0s] 8 rows retrieved
```

Even though it is only 8 rows, I watched it take over 5 minutes.

No source file, test, or entry point is named in the issue. Start by reproducing the reported fetch for the same room and comparing the displayed zero-second value with the observed duration; done means the timing output accurately reflects the database fetch or the discrepancy is clearly explained.
