Support timezones

[joelmellon]

When outputting next run time, scheduler timezones aren't recognized. There are two techniques for setting timezone listed in the docs: https://laravel.com/docs/7.x/scheduling#timezones

I don't have much time to work on something like this, but I thought it might be a useful feature request.

Timezones should be handled when calculating next run, see:

laravel-schedule-list/src/ScheduleEvent.php

Lines 75 to 77 in 9577615

	if ($this->timezone) {
	$nextRun->setTimezone($this->timezone);
	}

I don't use timezones myself so I have not tested it in a real application.
Could this be that it only handles one of the techniques for setting timezone?

@hmazter You're right. It does see the timezone, but it appears as if the timezone has been applied backward. 00:00 Los Angeles is 07:00 UTC, but this says 17:00 which is 10:00 Los Angeles. It looks like it's subtracting 7 instead of adding it. Am I losing my mind?
