# Description
This small change allows tables to be grouped by date. It was previously
failing because nushell didn't know how to represent the date as a
string. This change allows the date to be formatted in rfc3339 format
with subseconds represented as dot milliseconds. This formatted datetime
representation is already understood by nushell.
Now you can do things like
### Grouping by the exact time
```
> ls | group-by modified | table

### Grouping and Displaying only the date (you could do this before this
PR too)
```

# Tests + Formatting
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass
# After Submitting
If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
