日期与Firebase的时间戳 [英] Date vs Timestamp for Firebase

问题描述

您是否建议在datetime和时间戳之间使用 Firebase 存储日期，以及为什么？

What would you recommend to store dates using Firebase between a datetime and a timestamp, and why?

推荐答案

使用时间戳，因为这是locale-agnostic，不需要客户端之间的格式化和解析协议。它也有点短。

Use a timestamp as this is locale-agnostic and does not require formatting and parsing agreements between clients. It's also a bit shorter.

此外，请使用 Firebase.ServerValue.TIMESTAMP ，而不是相信客户端的时钟设置不正确。例如，如果客户端的时钟关闭了5分钟，并且您在聊天对话中使用客户端时间戳，则会将消息退回，否则其他用户将来会显示5分钟。

Furthermore, utilize Firebase.ServerValue.TIMESTAMP, rather than trusting the clients to have their clocks set incorrectly. If, for example, a client's clock is off by 5 minutes and you utilize the client timestamps in a chat conversation, then rendering back the messages, the time shown would appear to be 5 minutes in the future for other users.
