在 ruby​​ 中表示没有日期的时间

2021-12-23 00:00:00 datetime time ruby-on-rails ruby mysql

有没有办法在不附加日期的情况下用 ruby​​ 表示时间?我正在做一个时间跟踪应用程序,我只需要进/出时间,有一个单独的日期列.

Is there a way to represent a time in ruby without having a Date attached? I am doing a timetracking application and I only need in/out times, there is a separate column for date.

MySQL TIME 数据类型仅存储时间,但在 Rails 中,它返回为 2000 年 1 月 1 日 + 任何时间.

The MySQL TIME data type stores only the time, but in Rails it comes back as Jan 1 2000 + what ever time is there.

我应该忽略日期部分,还是有办法消除它?

Should i just ignore the date part, or is there a way to eliminate it?

推荐答案

没有办法消除它,因为:

时间在内部存储为自 1970 年 1 月 1 日 00:00 UTC 以来的带分数的秒数.

Time is stored internally as the number of seconds with fraction since the Epoch, January 1, 1970 00:00 UTC.

就这样格式化:

t = Time.now
t.strftime("at %I:%M%p")
