Description:

I want to show the Time reflecting the selected time zone from User..

NovaServiceProvider
*/

    public function boot()
    {
        parent::boot();
        $this->getNovaMenu();
        Nova::userTimezone(function (Request $request) {
            return $request->user()?->time_zone; // There is a filed in database 'time_zone'
        });
    }

Resource View

            DateTime::make('Presence', 'presence')->displayUsing(function ($value) use ($request) {
               return $value?->format('l / h:i');
            })->sortable(),

Display dos not respect the timezone user selects , to solve this, for now, am using :

            DateTime::make('Presence', 'presence')->displayUsing(function ($value) use ($request) {
                if($value)
                {
                    return sprintf('%s', Carbon::parse($value)->setTimezone($request->user()->time_zone ?: 'UTC')->format('l / h:i'));
                }
                return null;
            })->sortable(),

This is expected behavior for Laravel Nova 4.

Then what is the benefit of "Nova::userTimezone"! if I will change each DatTime timezone by hand!

[crynobone]

You are only required if you use displayUsing(), The current behavior is that every value is output using application timezone using ISO 8601 format and converted to user timezone on the front end.

Changing this on patch release can also cause breaking changes to components depending on this setup.
