如何使用偏移量將 YYYYMMDDHHMMSS 轉換為 UTC

JavaScript

慕村225694 2023-07-06 16:39:20

我在具有 localTimeStamp 和 UTC 偏移量的對象中獲取日期，如下所示。obj = { "localTimeStamp": 20200908232201 //YYYYMMDDHHMMSS "utcTimeOffset" : "+0630"}如何將其轉換為本地日期時間 - 格式 DD-MM-YYYY HH:MM:SSUTC 日期時間 - 格式 DD-MM-YYYY HH:MM:SS我嘗試過以下解決方案，但如何在 UTC 中轉換。"20200908232201".replace(/^(\d{4})(\d\d)(\d\d)(\d\d)(\d\d)(\d\d)$/,'$2-$3-$1 $4:$5:$6');

如果您不想使用任何庫，那么您可以嘗試以下方法：

您已經有了所需格式的日期 - (DD-MM-YYY HH:MM:SS)。

let utcTimeOffset = '+0630';

var d = new Date(

'20200908232201'.replace(

/^(\d{4})(\d\d)(\d\d)(\d\d)(\d\d)(\d\d)$/,

'$2-$3-$1 $4:$5:$6'

) + utcTimeOffset

);

然后使用UTC上述日期將日期轉換為 UTC：

var utcDate = new Date(

Date.UTC(

d.getUTCFullYear(),

d.getUTCMonth(),

d.getUTCDate(),

d.getUTCHours(),

d.getUTCMinutes(),

d.getUTCSeconds()

)

);

最后使用以下格式以所需的格式打印日期 -

var MyDateString =

('0' + utcDate.getUTCDate()).slice(-2) +

'-' +

('0' + (utcDate.getUTCMonth() + 1)).slice(-2) +

'-' +

utcDate.getUTCFullYear() +

' ' +

('0' + utcDate.getUTCHours()).slice(-2) +

'-' +

('0' + utcDate.getUTCMinutes()).slice(-2) +

'-' +

('0' + utcDate.getUTCSeconds()).slice(-2);

console.log(MyDateString); //08-09-2020 16-52-01

let utcTimeOffset = '+0630';

var d = new Date(

'20200908232201'.replace(

/^(\d{4})(\d\d)(\d\d)(\d\d)(\d\d)(\d\d)$/,

'$2-$3-$1 $4:$5:$6'

) + utcTimeOffset

);

var utcDate = new Date(

Date.UTC(

d.getUTCFullYear(),

d.getUTCMonth(),

d.getUTCDate(),

d.getUTCHours(),

d.getUTCMinutes(),

d.getUTCSeconds()

)

);

var MyDateString =

('0' + utcDate.getUTCDate()).slice(-2) +

'-' +

('0' + (utcDate.getUTCMonth() + 1)).slice(-2) +

'-' +

utcDate.getUTCFullYear() +

' ' +

('0' + utcDate.getUTCHours()).slice(-2) +

'-' +

('0' + utcDate.getUTCMinutes()).slice(-2) +

'-' +

('0' + utcDate.getUTCSeconds()).slice(-2);

console.log(MyDateString);

您可以嘗試使用Luxon庫，它實際上是 moment.js 的繼承者，并且具有許多強大的日期處理功能。

特別是，我們可以使用DateTime.fromFormat函數來解析提供的日期。

const DateTime = luxon.DateTime;

const obj = {

? ? ?"localTimeStamp": 20200908232201, //YYYYMMDDHHMMSS

? ? ?"utcTimeOffset" : "+0630"

}

const dt = DateTime.fromFormat(obj.localTimeStamp + obj.utcTimeOffset, "yyyyMMddHHmmssZZZ", { setZone: true } );

console.log("Local time:", dt.toISO())

console.log("UTC Time:", dt.toUTC())

您可以對 localTimeStamp 進行切片

const obj = {

? ? "localTimeStamp": "20200908232201",

? ? "utcTimeOffset": "+0630"

};

let localTimeStamp = obj.localTimeStamp;

let utcTimeOffset = obj.utcTimeOffset;

let formattedDate = new Date(localTimeStamp.slice(0, 4), localTimeStamp.slice(4, 6) - 1, localTimeStamp.slice(6, 8), localTimeStamp.slice(8, 10), localTimeStamp.slice(10, 12), localTimeStamp.slice(12, 14));

let formattedDateToLocal = new Date(formattedDate + utcTimeOffset);

let formattedDateToUTC = new Date(formattedDate.toUTCString() + utcTimeOffset);

? ?

console.log(`UTC : ${formattedDateToUTC.getDate()}-${formattedDateToUTC.getMonth()}-${formattedDateToUTC.getFullYear()} ${formattedDateToUTC.getHours()}:${formattedDateToUTC.getMinutes()}:${formattedDateToUTC.getSeconds()}`)

console.log(`Local : ${formattedDateToLocal.getDate()}-${formattedDateToLocal.getMonth()}-${formattedDateToLocal.getFullYear()} ${formattedDateToLocal.getHours()}:${formattedDateToLocal.getMinutes()}:${formattedDateToLocal.getSeconds()}`)

const obj = {

localTimeStamp: 20200908232201,

utcTimeOffset : "+0630"

};

const date = new Date((new Date(obj.localTimeStamp)).toUTCString() + obj.utcTimeOffset);

console.log(date.toUTCString());

console.log(date.toLocaleString());
