* Wait, I'm trying to get `defmt` timestamps in my logs.
I thought the only thing I had to do was to add the `defmt::timestamp!` macro.

But I still get no timestamps and I get a warning from probe-run:
```
WARN  `defmt::timestamp!` implementation was found, but timestamp is not part of the log format; consider adding the timestamp `{t}` argument to the log format
```
