Laravel-如何根据时区检查Carbon上两个时间戳之间的差异

Question

我想找出不同时区的2次之间的差异。 我可以使用存储在我们数据库中的2次字符串，并根据设置的时区和2次（$timeFrom＆amp; $timeTo）运行cron作业。

$timezone = $timezone // like (UTC)
$timeFrom = $timeFrom // like 09:00:00
$timeTo = $timeTo // like 01:00:00

date_default_timezone_set($timezone);
$currentTime = Carbon::now();
$timeFrom = Carbon::parse($timeFrom)->minute(0)->second(0);
$dateExplode = explode(':',$timeTo);
$checkDate = ltrim($dateExplode[0],'0');

if($checkDate > 0 && $checkDate < 12){
   $timeTo = Carbon::parse($timeTo)->minute(0)->second(0)->addDay();
} else {
   $timeTo = Carbon::parse($timeTo)->minute(0)->second(0);
}

$check = $currentTime->between($timeFrom,$timeTo); // result TRUE/FALSE

当我使用between运行cron用户时区时。我错过了什么？
