I want to move away from supporting/recommending the use of (SHORT_)?DATE(TIME?)_FORMAT in Nautobot. This involves deprecating or removing the use of (SHORT_)?DATE(TIME?)_FORMAT in favor of more flexible and locale-based date and time formatting options. Specifically, we should prioritize locale-driven formatting when USE_L10N is set to True and encourage developers to rely on these standardized formats rather than hardcoding (SHORT_)?DATE(TIME?)_FORMAT.

So that ...

By removing reliance on (SHORT_)?DATE(TIME?)_FORMAT, we promote greater localization and ensure that the application behaves according to the user's regional preferences for date and time formats. This will reduce the need for custom formatting logic and provide a more user-friendly experience for users across different regions.

Additionally USE_L10N is on by default in Django 4 and going to be always-on when we move to Django 5 (https://docs.djangoproject.com/en/5.1/releases/5.0/#features-removed-in-5-0)

I know this is done when...

• Remove all of the (SHORT_)?DATE(TIME?)_FORMAT references in our code and our docs and instead document how to set the locale appropriately to get the desired behavior.
• Unit tests are updated to ensure that date and time formatting behaves correctly according to locale settings (using USE_L10N).

Optional - Feature groups this request pertains to.

• Circuits
• DCIM
• IPAM
• Misc (including Data Sources)
• Organization
• Apps (and other Extensibility)
• Security (Secrets, etc)
• Image Management
