Laravel Carbon 如何在不更改小时的情况下更改时区

Ok, I figured out a dumb, but functional way of doing what I wanted to do, and it works.

这是我的代码:

      $dt = Carbon::parse($request->ShootDateTime)->timezone('America/Los_Angeles');
      $toDay = $dt->format('d');
      $toMonth = $dt->format('m');
      $toYear = $dt->format('Y');
      $dateUTC = Carbon::createFromDate($toYear, $toMonth, $toDay, 'UTC');
      $datePST = Carbon::createFromDate($toYear, $toMonth, $toDay, 'America/Los_Angeles');
      $difference = $dateUTC->diffInHours($datePST);
      $date = $dt->addHours($difference);

I get the time I wanted to convert to a timezone and parse it and change the timezone. I then get the Day, Month, and Year and create 2 different Dates, both will read as being 00:00:00 in time, but because they are separate by 7 hours in this instance, they can only both be 00:00:00 if they are 7 hours different, which is what I capture next. Then finally, I take the initial datetime and add the difference to it, giving me the proper time in the proper timezone.

It's ugly, but it works.
