我写了一个包https://github.com/ringsaturn/tzf支持获取时区在Go&Python和非常快:

package main

import (
    "fmt"

    "github.com/ringsaturn/tzf"
)

func main() {
    finder, err := tzf.NewDefaultFinder()
    if err != nil {
        panic(err)
    }
    fmt.Println(finder.GetTimezoneName(116.6386, 40.0786))
}

Python https://github.com/ringsaturn/tzfpy sample:

from tzfpy import get_tz

print(get_tz(121.4737, 31.2305))

Rust https://github.com/ringsaturn/tzf-rs样品:

use tzf_rs::DefaultFinder;

fn main() {
    let finder = DefaultFinder::new();

    print!("{:?}\n", DefaultFinder.get_tz_name(116.3883, 39.9289));
}

node.js的这个解决方案怎么样 https://github.com/mattbornski/tzwhere

和它的Python对等体: https://github.com/pegler/pytzwhere

时区位置Web服务

谷歌映射时区API 必应地图时区API Azure地图时区API GeoNames时区API TimeZoneDB API AskGeo -商业(但可以说比GeoNames更准确) 地理车库时区API -商业，专注于航海时区。

原始时区边界数据

Timezone Boundary Builder -从OpenStreetMaps地图数据中构建时区形状文件。包括海岸线附近的领海。

以下项目以前是时区边界数据的来源，但不再积极维护。

tz_world -来自Eric Muller的原始shapefile数据 whereonearth-timezone - GeoJSON版本与WOEDB数据合并

时区地理定位离线实现

使用时区边界生成器数据的实现

node-geo-tz - JavaScript library (Node.js only) timespace - JavaScript library tz-lookup-oss - JavaScript library GeoTimeZone - .NET library Geo-Timezone - PHP library timezonefinder - Python library ZoneDetect - C library Timeshape - Java library TimeZoneMap - Java and Android library lutz - R library go-tz - Go library Timezone lookup - Go library docker-timezone-lookup - docker container wrapping node-geo-tz tzf - Go library tzfpy - Python port of tzf library tzf-rs - Rust port of tzf library

使用较旧的tz_world数据的实现

latlong - Go库(也可以阅读这篇文章)。 TimeZoneMapper - Java库 tzwhere - JavaScript/节点库 pytzwhere - Python库 timezone_finder - Ruby库 LatLongToTimeZone - Java和Swift库 现在几点了?-描述PHP和MongoDB的博客文章 rundel/timezone - R库

调用其中一个web服务的库

timezone -调用GeoNames的Ruby宝石 AskGeo有自己的库，用于从Java或。net进行调用 GeoNames拥有几乎所有东西的客户端库

自托管web服务

geo2tz -基于时区查找，可通过Docker image获得

其他的想法

找到最近有R-Tree的城市 用MySQL找到最近的城市

如果您知道其他名单，请更新此名单

此外，请注意，最近的城市方法可能不会产生“正确”的结果，只是一个近似值。

转换到Windows区域

列出的大多数方法都将返回IANA时区id。如果您需要转换为Windows时区，以便与。net中的TimeZoneInfo类一起使用，请使用TimeZoneConverter库。

不要使用zone.tab

tz数据库包含一个名为zone.tab的文件。该文件主要用于显示时区列表，供用户从中选择。它包括每个时区参考点的纬度和经度坐标。这允许创建一个突出显示这些点的地图。例如，查看moment-timezone主页上显示的交互式地图。

虽然使用这些数据从纬度和经度坐标解析时区可能很诱人，但请考虑这些是点，而不是边界。最好的办法是确定最近的点，但在许多情况下，这并不是正确的点。

考虑下面的例子:

这两个方格表示不同的时区，其中每个方格中的黑点是参考位置，例如在zone.tab中可以找到的位置。蓝点表示我们试图为其寻找时区的位置。显然，这个位置位于左侧的橙色区域内，但如果我们只看距离参考点最近的距离，它将解析为右侧的绿色区域。

如果你不想使用web服务，你可以像这样从浏览器中检索信息:

var d = new Date();
var usertime = d.toLocaleString();

//some browsers / OSs provide the timezone name in their local string
var tzsregex = /\b(ACDT|ACST|ACT|ADT|AEDT|AEST|AFT|AKDT|AKST|AMST|AMT|ART|AST|AWDT|AWST|AZOST|AZT|BDT|BIOT|BIT|BOT|BRT|BST|BTT|CAT|CCT|CDT|CEDT|CEST|CET|CHADT|CHAST|CIST|CKT|CLST|CLT|COST|COT|CST|CT|CVT|CXT|CHST|DFT|EAST|EAT|ECT|EDT|EEDT|EEST|EET|EST|FJT|FKST|FKT|GALT|GET|GFT|GILT|GIT|GMT|GST|GYT|HADT|HAEC|HAST|HKT|HMT|HST|ICT|IDT|IRKT|IRST|IST|JST|KRAT|KST|LHST|LINT|MART|MAGT|MDT|MET|MEST|MIT|MSD|MSK|MST|MUT|MYT|NDT|NFT|NPT|NST|NT|NZDT|NZST|OMST|PDT|PETT|PHOT|PKT|PST|RET|SAMT|SAST|SBT|SCT|SGT|SLT|SST|TAHT|THA|UYST|UYT|VET|VLAT|WAT|WEDT|WEST|WET|WST|YAKT|YEKT)\b/gi;

//in other browsers the timezone needs to be estimated based on the offset
var timezonenames = {"UTC+0":"GMT","UTC+1":"CET","UTC+2":"EET","UTC+3":"EEDT","UTC+3.5":"IRST","UTC+4":"MSD","UTC+4.5":"AFT","UTC+5":"PKT","UTC+5.5":"IST","UTC+6":"BST","UTC+6.5":"MST","UTC+7":"THA","UTC+8":"AWST","UTC+9":"AWDT","UTC+9.5":"ACST","UTC+10":"AEST","UTC+10.5":"ACDT","UTC+11":"AEDT","UTC+11.5":"NFT","UTC+12":"NZST","UTC-1":"AZOST","UTC-2":"GST","UTC-3":"BRT","UTC-3.5":"NST","UTC-4":"CLT","UTC-4.5":"VET","UTC-5":"EST","UTC-6":"CST","UTC-7":"MST","UTC-8":"PST","UTC-9":"AKST","UTC-9.5":"MIT","UTC-10":"HST","UTC-11":"SST","UTC-12":"BIT"};

var timezone = usertime.match(tzsregex);
if (timezone) {
    timezone = timezone[timezone.length-1];
} else {
    var offset = -1*d.getTimezoneOffset()/60;
    offset = "UTC" + (offset >= 0 ? "+" + offset : offset);
    timezone = timezonenames[offset];
}

//there are 3 variables can use to see the timezone
// usertime - full date
// offset - UTC offset time
// timezone - country

console.log('Full Date: ' + usertime);
console.log('UTC Offset: ' + offset);
console.log('Country Code Timezone: ' + timezone);

在我目前的情况下，它是打印:

日期:“27”/“01”/“2014”:“16”:“53”:“37” UTC偏移量:UTC-3 国家代码时区:BRT

希望对大家有所帮助。
