一个名字。欢迎来到StackOverflow！仅仅发布一个链接，而没有相关的代码示例，并没有太大的帮助。请尽量避免只发布没有进一步信息的链接。不幸的是，此库不是最新的，因此某些时区可能被错误地检测到。@Gujamin:很遗憾，你是对的。看起来Safari完全忽略了所提供的选项对象，而Chrome和其他有礼貌的浏览器都很礼貌地对待它。有人知道一种以长字符串格式获取时区的简明跨平台方法吗？我最后只使用了user3119287的答案。虽然不理想，但它确实有效。即使在IE中也不起作用。它没有给出时区name@KevalBhatt-很好！关于时区选择器的问题，我会记住这一点。这是一个很好的替代我上面链接的一个。谢谢<代码>（新日期）.toString（）.split（“（”）[1].slice（0，-1）@Sami-这不可靠。结果可能是任何结果。不同浏览器的实现差异很大，并且没有关于Intl.DateTimeFormat（）.resolvedOptions（）的兼容性的规范，这似乎是目前最好的选择。谢谢！为什么我们需要两个参数（夏季偏移量、冬季偏移量）？@PhucNguyen一些时区遵守夏令时，其他的不遵守。这就像宝莱坞电影一样！
