我需要转换以下日期时间格式:
Start: {
DateTime: '2016-09-01T03:00:00.0000000',
TimeZone: 'Etc/GMT+2'
},
转换为 unix 时间戳 1472691600000。
即使输入时区发生变化，此转换也应该有效。
这是我通过 Office365 API 获取的数据。在 Office365 日历(在浏览器中)中，我将事件设置为 8:00 UTC+2 开始。
我一段时间以来一直在尝试寻找此问题的解决方案，因此我们将不胜感激。
最佳答案
时间戳是有效的 ISO 8601 日期时间，因此我们可以简单地使用 javascript 的 Date.parse() 将其解析为 unix 时间戳。
但是，时区似乎是 POSIX 时区。正如 this StackOverflow answer 所说，Etc/GMT+2 应转换为 GMT-2(ISO 8601 中的 -0200)，而不是 +2。
如果时间戳可以更改，则意味着我们应该有一个 list of all valid timestamps 。我编写了一个简单的解析器来获取 JS 可解析格式的时间戳:
find ./* -exec grep ^Zone {} \; | awk '{print $2" "$3}' | awk -F '[ :]' '{ printf "\"%s\": \"%+03.0f%02.0f\"\n", $1, $2, $3 }'
这会输出格式化的时区，我们可以将其用作 JS 数组。这样我们就可以将 POSIX 时区转换为 ISO 8601 时区格式。
最终的代码是:
function convertToTimestamp(datetimeObject) {
var timezones = {

var isoDateFormat = datetimeObject.Start.DateTime + timezones[datetimeObject.Start.TimeZone];
return Date.parse(isoDateFormat);
}
您可以将其用于:
var timestampObject = {
Start: {
DateTime: '2016-09-01T03:00:00.0000000',
TimeZone: 'Etc/GMT+2'
}
};
convertToTimestamp(timestampObject); // Outputs 1472706000000
