如何从 Unix 时间戳计算本地时间
如果全世界的 Unix 时间戳都相同，我如何才能获得本地时间.
If unix timestamp is the same across the world how is am I able to get local time.
或者是基于不同的时区时间戳不同.即我在美国，从 UTC 1970 开始的当前秒数是 5,000，但如果我在亚洲并检查时间戳，它将是 4,000 秒?
Or is it based on the different timezones the timestamp is different. i.e. I am in US the current seconds from UTC 1970 is 5,000 but if I am in Asia and check timestamp it will be 4,000 seconds ?
UTC 在世界上每个国家都是一样的，无论你在美国还是在亚洲，这个值都是一样的.
UTC is the same for every country in the world, whether you check in the US or in Asia the value will be the same.
本地时间是通过使用时区偏移量计算的(通常通过 IANA 时区数据库提供一>).将其添加到 UTC 时间以确定自 1970 年以来的本地时间".
Local time is calculated by using a time-zone offset (usually provided through the IANA time zone database). This is added to UTC time to determine the "Local Time" since 1970.
