1.week.ago.in_zone(Time.zone) for Rails? [英] 1.week.ago.in_zone(Time.zone) for Rails?

问题描述

有没有办法在不这样做的情况下在特定时区使用那些花哨的时间助手方法?

Is there a way to use those fancy time helper methods in specific time zones without doing this?

Time.use_zone(Time.zone.name) { 1.week.ago }

我应该向哪个类添加 in_zone 方法，以便我可以在不引起太多混乱的情况下执行以下操作?

What class(es) should I add a in_zone method to so I can do the following without causing too much confusion?

1.week.ago.in_zone(Time.zone.name)

还是已经内置了?我想知道，因为我在任何地方都使用 Time.zone.now 并且想要一种更简单的方法来处理其他情况.

Or is this already built in? I'm wondering because I use Time.zone.now everywhere and would like a simpler way of doing it on those other cases.

Rails 有一个方法叫做 in_time_zone 为您执行此操作.它适用于任何 Time、Date 或 ActiveSupport::TimeWithZone 对象..

Rails has a method called in_time_zone which does this for you. It works on any Time, Date or ActiveSupport::TimeWithZone object..

1.week.ago.in_time_zone("Tokyo")
