How to convert any time zone into UTC using Laravel-CodePudding

I want to convert the user's time, eg. 08:45 P.M, to UTC time zone. How can I do that?

if ($request->open_at)
{
  $time = Carbon::parse($request->open_at)->toUTCString();
  dd($time);
  $query->whereTime('open_at', '>=', $time);
}

CodePudding user response：

Like such, but unless you're always starting from the system timezone (configured in PHP), date must already have the correct timezone set for this to work, like others have mentioned.

$time = Carbon::parse($request->open_at);
$time->setTimezone('UTC');
...

Carbon extends the DateTime object including setTimezone

CodePudding user response：

Use this PHP approach:

$time = new DateTime("08:45 P.M");
$time ->setTimezone(new DateTimeZone("UTC"));
echo $time ->format("Y-m-d H:i:s e");

CodePudding user response：

Carbon has ->utc() method (equivalent to setTimezone('UTC')) and Laravel query build can take Carbon object without having to format it as a string:

$query->whereTime('open_at', '>=', Carbon::parse($request->open_at)->utc());

CodePudding user response：

Use the set timezone function to convert time

$time = Carbon::parse($request->open_at);
$time->setTimezone('UTC');
