只比较时间，没有日期? [英] Comparing times only, without dates?

问题描述

我需要编写一个方法来检查 Time.now 是否在商店的营业时间和关闭时间之间.

I need to write a method that will check if Time.now is in between the open hours and the close hours of a shop.

营业时间和营业时间都保存为 Time 对象，但我无法正确比较它，因为商店将营业时间保存在 2012/2/2，因此营业时间将类似于:

The open and close hours are saved as a Time object but I can't compare it corectly because the shop saved its hours at 2012/2/2 so the open hours will be something like:

2012-02-02 02:30:00 UTC

和 Time.now 将是:

07:23 +0200

如何只比较时间部分而不比较日期部分?

How can I compare just the time part without the date part?

推荐答案

可以比较Time不带日期部分，例如如下:

You can compare the Time without a date part, for example, as follows:

time1.utc.strftime( "%H%M%S%N" ) <= time2.utc.strftime( "%H%M%S%N" )
