将unix timestmp转换为日期

import datetime

dt_object = datetime.datetime.fromtimestamp(timestamp)
print(dt_object)

const timestamp = 1633022400;
const date = new Date(timestamp * 1000);
console.log(date);

import java.time.Instant;

    public static void main(String[] args) {
        long timestamp = 1633022400L;
        LocalDateTime dateTime = LocalDateTime.ofInstant(Instant.ofEpochSecond(timestamp), ZoneId.systemDefault());
        System.out.println(dateTime);
    }
}

$timestamp = 1633022400;
$date = date("Y-m-d H:i:s", $timestamp);
echo $date;
