帮助显示时间 [英] Help Displaying Time
问题描述
我想在特定时区（美国中部）显示时间，无论计算机所在的位置是什么。我写了下面的脚本
显示了美国东部，中部，山区，太平洋和阿拉斯加时间区域的时间
区域。如果计算机位于中央
时区，但如果它位于其他地方，则无效。我知道如何获得UTC时间
和timezoneOffset但是我不知道如何从那里到
中央时间。任何人都可以提供任何建议吗？

I want to display the time in a particular timezone (US Central) regardless
where the computer is located. I have written the script below which
displays the time in the Eastern, Central, Mountain, Pacific and Alaska time
zones in the US. It works okay if the computer is located in the Central
timezone but not if it is located elsewhere. I know how to get the UTC time
and the timezoneOffset but I can''t figure out how to get from there to
Central time. Can anyone offer any suggestions?

推荐答案
我认为日期中有一个函数setTimeZoneOffset（）
的对象允许你设置GMT的小时偏差（一般平均时间即格林威治
英格兰）
I think there is a function setTimeZoneOffset() of the Date object that
lets you set hours of offset from GMT (general mean time i.e. greenwich
england)

如果您知道TimezoneOffset，并且您知道CT是-6GMT（忽略
DST），并且某些位置' '偏移包括一小时的分数
（这将影响小时和分钟），你可以计算CT。
now = new Date（）;
now.setHours（now.getHours（）+（now.getTimezoneOffset（）/ 60）-6）;

If you know the TimezoneOffset, and you know that CT is -6GMT (ignoring
DST), and that some locations'' offsets include fractions of an hour
(this will effect the hrs and mins), you may compute CT.
now=new Date();
now.setHours(now.getHours()+(now.getTimezoneOffset ()/60)-6);

他们如何拥有一小时的分数？我上次检查时区是坚实的时间。
How do they have fractions of an hour? Timezones are solid hour by
hour last time I checked.
