如何将UTC DateTime转换为本地DateTime，而不会以不同的格式转换

我有这种格式的特定日期时间值' yyyy-mm-ddthh：mm：ss.ms '（eg' 2022-05-10T13：44：00.0000000 '）我需要将它们转换为本地DateTime（对我来说是UTC+2），而不会更改格式（So' 2022-05-10T15：44：00.0000000 '是所需的结果（甚至更好的结果是更好没有毫秒，但这只是锦上添花）。

我已经搜索了很广泛的搜索，但是我发现的每一个所谓的解决方案都会更改格式，或者根本不会改变时间。

这就是我现在拥有的，它成功地将时间转换为本地时间，但是通过.toisostring（）将原始格式运行以使其转换回UTC时间。

//Input: event.start.dateTime = '2022-05-10T13:44:00.0000000'

let startDateTime = new Date(event.start.dateTime);
startDateTime.setMinutes(startDateTime.getMinutes() - 
startDateTime.getTimezoneOffset());
document.getElementById('ev-start').value = 
startDateTime.toISOString().slice(0,16);

//Output: '2022-05-10T13:44:00.000Z'

I have specific DateTime values in this format 'YYYY-MM-DDThh:mm:ss.ms' (e.g. '2022-05-10T13:44:00.0000000') and I need to convert them to local DateTime (which is UTC+2 for me) without changing the format (so '2022-05-10T15:44:00.0000000' is the desired result (even better would be without the milliseconds but that would just be the icing on the cake)).

I've searched far and wide but every alleged solution I find either changes the format or doesn't change the time at all.

This is what I have right now, it successfully converts the time to local time but by running it through .toISOString() to get the original format back it converts it back to UTC time.

//Input: event.start.dateTime = '2022-05-10T13:44:00.0000000'

let startDateTime = new Date(event.start.dateTime);
startDateTime.setMinutes(startDateTime.getMinutes() - 
startDateTime.getTimezoneOffset());
document.getElementById('ev-start').value = 
startDateTime.toISOString().slice(0,16);

//Output: '2022-05-10T13:44:00.000Z'

我找不到一个干净且令人满意的解决方案，所以我决定自己的格式。这是我最终得到的：

输入：' 2022-05-10T13：44：00.0000000 '

let startDateTime = new Date(event.start.dateTime);
startDateTime.setMinutes(startDateTime.getMinutes() - 
startDateTime.getTimezoneOffset());
let localStartDateTime = startDateTime.getFullYear() + "-" + 
       (startDateTime.getMonth() + 1).toString().padStart(2, '0') +
       "-" + startDateTime.getDate().toString().padStart(2, '0') + 
       "T" + startDateTime.getHours().toString().padStart(2, '0') + 
       ":" + startDateTime.getMinutes().toString().padStart(2, '0') 
       + ":" +
       startDateTime.getSeconds().toString().padStart(2, '0');
       document.getElementById('ev-start').value = 
       localStartDateTime;

输出：' 2022-05-10T15：44：00 ''

I couldn't find a clean and satisfying solution so I decided to just to the formatting myself. Here's what I ended up with:

Input: '2022-05-10T13:44:00.0000000'

let startDateTime = new Date(event.start.dateTime);
startDateTime.setMinutes(startDateTime.getMinutes() - 
startDateTime.getTimezoneOffset());
let localStartDateTime = startDateTime.getFullYear() + "-" + 
       (startDateTime.getMonth() + 1).toString().padStart(2, '0') +
       "-" + startDateTime.getDate().toString().padStart(2, '0') + 
       "T" + startDateTime.getHours().toString().padStart(2, '0') + 
       ":" + startDateTime.getMinutes().toString().padStart(2, '0') 
       + ":" +
       startDateTime.getSeconds().toString().padStart(2, '0');
       document.getElementById('ev-start').value = 
       localStartDateTime;

Output: '2022-05-10T15:44:00'

希望这会有所帮助

const startDateTime = new Date('2022-05-10T13:44:00.0000000');

const outputDateTime = new Date(startDateTime.toString()).toISOString().slice(0, 19);

//document.getElementById('ev-start').value = outputDateTime

console.log(outputDateTime);

Hope this helps

const startDateTime = new Date('2022-05-10T13:44:00.0000000');

const outputDateTime = new Date(startDateTime.toString()).toISOString().slice(0, 19);

//document.getElementById('ev-start').value = outputDateTime

console.log(outputDateTime);
