Make Rolex show time (#2147)

* show time when robot has `time` capability

Prompted by #2146, which used the fancy `rolex` entity for commands but surprisingly did not show time in UI.

You can test it with:
```sh
git cherry-pick ba8dae3  # see before and after adding rolex
cabal run swarm -O0 -- -i data/scenarios/Testing/562-lodestone.yaml --speed 2 --autoplay
```
