无法在 javascript 中将字符串 BST 日期格式转换为 UTC

Question

我有一个类似于07-Oct-2019 11:02BST 格式的字符串。我必须以相同的格式转换为 UTC 时间，这将是07-Oct-2019 10:02.

我尝试了很多方法并试图找到一些内置功能，但没有任何效果。我尝试编写一个函数，该函数将拆分字符串，然后将其转换为日期和 UTC，但这也不起作用。

这是我尝试过的

var fullDate = "07-Oct-2019 11:02";

            fullDate = fullDate.split(' ');

            var date = fullDate[0].split("-");

            var time = fullDate[1];

            var newDate = date[0] + '-' + date[1] + '-' + date[2] + ' ' + time;

            var k = new Date(newDate);

            alert(d);

但是这个结果变成当前日期变成 IST 。

请帮助我如何做到这一点。

我正在使用 DOJO 框架。

使用moment-timezone对日期和时区进行高级操作。解决方案：let date = "07-Oct-2019 11:02"console.log(moment.tz(date, "DD-MMM-YYYY HH:mm", "Europe/London").utc().format("DD-MMM-YYYY HH:mm"));<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.1/moment.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.16/moment-timezone-with-data.min.js"></script>
