# User-Facing Changes
The ``into datetime`` command will now work with formatting and time
zones or offset together

# Tests + Formatting
Fmt + clippy OK

**Note about the tests I added**: those tests don't really test my
changes, as they were already passing before my changes. Nevertheless I
thought I could push them

### Background on nu-cmd-lang
This crate was designed to be a small, concise set of tools or commands that serve as the *foundation layer* of both nu and nushell. These are the core commands needed to have a nice working version of the *nu language* without all of the support that the other commands provide inside nushell. Prior to the launch of this crate all of our commands were housed in the crate *nu-command*. Moving forward we would like to *slowly* break out the commands in nu-command into different crates; the naming and how this will work and where all the commands will be located is a "work in progress" especially now that the *standard library* is starting to become more popular as a location for commands. As time goes on some of our commands written in rust will be migrated to nu and when this happens they will be moved into the *standard library*.
