从 ruby​​ 中的 UUID v1 中提取时间 [英] Extract time from a UUID v1 in ruby

问题描述

我存储了以 UUID v1 作为键的数据，现在我想知道 UUID 是何时生成的.我该如何做到这一点?

I have stored data that has a UUID v1 as key and I now want to know when the UUID was generated. How do I do that the nice way?

推荐答案

这适用于 irb:

require 'simple_uuid'
uuid = SimpleUUID::UUID.new
uuid.to_guid # actually this is what I have stored in my database
Time.at(SimpleUUID::UUID.new(uuid.to_guid).seconds) # returns the time and date of the UUID

感谢我的朋友 KillerFox，他向我展示了简单的解决方案.
