[WIP] - Feature/datetime work

[briandowns]

Datetime Module

What's Changed:

Refactor Datetime module to be class based and add additional features. This is marked as draft / WIP in order to get feedback on the implementation. If acceptable, I'll complete this with docs, tests, etc, as well as squash the commits down some more.

I added a "duration" object but I'm wanting to rethink it some. I can add that functionality in another PR.

Type of Change:

• [ ] Bug fix
• [x] New feature
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)

Housekeeping:

• [ ] Tests have been updated to reflect the changes done within this PR (if applicable).
• [ ] Documentation has been updated to reflect the changes done within this PR (if applicable).

Screenshots (If Applicable):

Sorry I've been slow on this! Looks as though all the tests are failing so we will need to look into these!

I'll get them passing. Just wanted to make sure the approach is ok.

Ah apologies mate! Yeah I like it, an object wrapper around the long value seems sensible to me :)
