DateTime fields should be displayed in the users local time

[jonespm]

Thank you for contributing to this project!

Describe your problem or feature you'd like added

It was noted that times displayed are local to a specific time on the server (America/Detroit by default) and it would probably be useful to have the times match what's in Canvas for the user to their local time. This is mostly for the assignment view.

Describe the solution you'd like

Either get and use the custom LTI launch variable Person.address.timezone or use the browsers time zone to do the time conversions for the user. This would require storing the times in UTC first locally via #1490

There is a library change in the Django upgrade that may affect this.

Here is the time zone related change with newest Django 4 upgrade.

Canvas provides the user's time zone in the variable $Person.address.timezone when LTIs are launched. A custom launch parameter can be set with this value.

Cron runs fine and no issues detected in beta testing.
