Twitter时区& created_at(世界标准时间)值可计算用户所在的时区 [英] Twitter timezone & created_at (utc time) values to calculate what time zone the user is in

问题描述

我试图基于给定tweet对象中的time_zone或created_at值来估计Twitter用户的位置.但是，似乎我遇到的所有created_at值都只是毫无意义的本地化时间，它们提供的时区并不是最有用的格式

I'm trying to estimate a twitter user's location based on the time_zone or created_at value in a given tweet object. However it seems that all created_at values I've come across are just in a pointless localised time and the time zone they supply isn't in the most helpful format

示例推文

"created_at":"Thu Jun 02 14:41:24 +0000 2011"
"time_zone":null

OR

"created_at":"Sun Jan 09 05:03:52 +0000 2011"
"time_zone":"Mountain Time (US & Canada)"

这两个时间都不是UTC时间，并且time_zone在世界其他地方也不是任何特定的标准格式

Both of these times aren't in UTC time and the time_zone isn't in any particular standard format with the rest of the world

我可能会遇到非常烦人的事情，我又累又热，并且一直在寻找这种解决方案太长时间了:|

I'm probably coming across really annoying, I'm tired and hot and been looking for this solution for too long :|

谢谢

推荐答案

此答案详细说明如何将Twitter日期转换为PHP可以使用的日期；概要如下.

This answer details how to convert a Twitter date into something PHP can work with; synopsis below.

strtotime("dateString");将其放入 本机PHP日期格式，然后您 可以与date()函数一起使用 印出您想要的方式.

strtotime("dateString"); gets it into the native PHP date format, then you can work with the date() function to get it printed out how you'd like it.

对于时区，可以使用user对象的utc_offset属性的值进行计算.例如，我的个人资料的utc_offset是:

As for the time zone, you can use the value of the utc_offset property of the user object to calculate it. For example, my profile's utc_offset is:

"utc_offset":-21600

将该值除以3600，将得出-6，这是美国中部时区.这些将是绝对偏移量，并且不会更改时区是否符合夏令时.

Just divide that value by 3600 and that will give you -6, which is the US Central time zone. These will be absolute offsets and will not change whether the time zone honors daylight savings time.
