Question

我正在寻找建立一个提示用户时区的表单。我看过'谷歌方法'，它看起来效果很好。首先从下拉列表中选择一个国家/地区，然后根据选择，使用时区选项填充下拉列表。我一直在寻找一个拥有国家 - 时区关系的体面数据库，但似乎无法找到一个。有谁知道我在哪里找到一个？

Answer 1

您是否尝试过zoneinfo？ http://www.twinsun.com/tz/tz-link.htm

“公共域时区数据库包含代表全球许多代表性地点的当地时间历史的代码和数据。它会定期更新，以反映政治机构对时区边界，UTC偏移和这个数据库（通常称为tz或zoneinfo）被多个实现使用，包括GNU / Linux，FreeBSD，NetBSD，OpenBSD，Cygwin，DJGPP，AIX，Mac OS X，OpenVMS，Oracle中使用的GNU C库。数据库，Solaris，Tru64和UnixWare。“

希望有所帮助：）

Answer 2

官方映射位于zone.tab file的IANA time zone database。

此文件还有一个较新版本，其中包含多个国家/地区可能正在使用时区的情况。它也位于IANA时区数据库中，名为zone1970.tab。

Answer 3

使用Noda Time和.NET Framework Culture和TimeZoneInfo类我们设法创建了一个Json文件，其中包含以下条目，这对我们有用。

国家或地区名称
2LetterIsoCountryCode
3LetterIsoCountryCode
IANATimezones
WindowsTimezones

每个条目都包含每个国家/地区的可用时区列表。

Answer 4

访问http://www.iana.org/time-zones/repository/tz-link.html

下载数据文件。

检查文件iso3166.tab和zone.tab - 它们之间有你需要的一切。

Answer 5

timezonedb：https://timezonedb.com/

也可以提到。您可以去下载页面，找到最适合您项目的格式。

Answer 6

library(dplyr)
df %>%
    mutate(across(starts_with('mean'), ~ . - Ttime))

Answer 7

如果商业解决方案可以接受，您可以查看World Time Zone Database。

Answer 8

Ruby on Rails对时区使用以下映射：http://apidock.com/rails/TimeZone
