JS時間和時間戳的轉換

時間轉為時間戳

timeToTimestamp(time){
    let timestamp = Date.parse(time)
    return timestamp;
}

時間戳轉為本地時間

timestampToTime(timestamp){
　　let date = new Date(timestamp);
　　var YY = date.getFullYear() + '-';
　　var MM = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
　　var DD = (date.getDate() < 10 ? '0' + (date.getDate()) : date.getDate());
　　var hh = (date.getHours() < 10 ? '0' + date.getHours() : date.getHours()) + ':';
　　var mm = (date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()) + ':';
　　var ss = (date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds());
　　return YY + MM + DD +" "+hh + mm + ss;
}

　　

時間戳轉為UTC時間

timestampToUtc(timestamp){
    let date = new Date(timestamp);
    var YY = date.getUTCFullYear() + '-';
    var MM = (date.getUTCMonth() + 1 < 10 ? '0' + (date.getUTCMonth() + 1) : date.getUTCMonth() + 1) + '-';
    var DD = (date.getUTCDate() < 10 ? '0' + (date.getUTCDate()) : date.getUTCDate());
    var hh = (date.getUTCHours() < 10 ? '0' + date.getUTCHours() : date.getUTCHours()) + ':';
    var mm = (date.getUTCMinutes() < 10 ? '0' + date.getUTCMinutes() : date.getUTCMinutes()) + ':';
    var ss = (date.getUTCSeconds() < 10 ? '0' + date.getUTCSeconds() : date.getUTCSeconds());
    return YY + MM + DD +"T"+hh + mm + ss+".000Z";
}
