如何将Etc / GMT + 2时区中的时间戳转换为unix时间戳？
我需要转换下面的date时间格式：
Start: { DateTime: '2016-09-01T03:00:00.0000000', TimeZone: 'Etc/GMT+2' }, 到一个unix时间戳1472691600000 。
即使input时区发生变化，此转换也可以正常工作。
这是我通过Office365 API获取的数据。 在Office365日历（在浏览器中），我把我的事件从8:00 UTC + 2开始。
我一直在努力寻找解决scheme这一段，所以任何帮助将不胜感激。
时间戳是一个有效的ISO 8601date时间，所以我们可以简单地使用javascript的Date.parse()来parsing它到一个Unix时间戳。
但是，时区似乎是一个POSIX时区。 而且，当这个StackOverflow的回答指出， Etc/GMT+2应该翻译成GMT-2 （在ISO 8601中为-0200 ），而不是+2 。
如果时间戳可以更改，这意味着我们应该有一个所有有效的时间戳列表 。 我写了一个简单的parsing器来获取JSparsing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 }'
这将输出格式化的时区，我们可以使用JS数组。 这样我们可以将POSIX时区转换为ISO 8601时区格式。
最终的代码是：

isoDateFormat = datetimeObject.Start.DateTime + timezones[datetimeObject.Start.TimeZone]; return Date.parse(isoDateFormat); }
你可以使用它：
var timestampObject = { Start: { DateTime: '2016-09-01T03:00:00.0000000', TimeZone: 'Etc/GMT+2' } }; convertToTimestamp(timestampObject); // Outputs 1472706000000
Unix的时间戳是时区独立的，你可以参考这个问题 。
所以你只需要parsingDateTime字段内的内容，并使用.valueOf方法获取时间戳
moment("2016-09-01 03:00:00.0000000", "YYYY-MM-DD HH:mm:ss.SSSSSSS").valueOf()
将返回1472688000000
即使你想通过提供一个时区来得到时间戳，你也会得到相同的时间戳
moment("2016-09-01 03:00:00.0000000", "YYYY-MM-DD HH:mm:ss.SSSSSSS").tz("America/New_York").valueOf() >> 1472688000000 moment("2016-09-01 03:00:00.0000000", "YYYY-MM-DD HH:mm:ss.SSSSSSS").tz("America/Los_Angeles").valueOf() >> 1472688000000
