将具有UTC时间的变量转换为Seconds整数（Ruby）(Converting a variable with a UTC time to a Seconds integer (Ruby))

将具有UTC时间的变量转换为Seconds整数（Ruby）(Converting a variable with a UTC time to a Seconds integer (Ruby))

我有一个与它相关的UTC时间的变量，例如：

offer_ends_at => Sun, 25 Nov 2012 07:59:59 UTC +00:00,

我的目标是创建一个新变量，并将Time转换为秒整数。 我尝试过一些类似的方法

seconds = offer_ends_at.to_time.to_i

我最终获得了一段时间。 我在一个实际的整数之后，它包含到日期发生之前剩余的秒数。

I have a variable that has a UTC time tied with it, example:

offer_ends_at => Sun, 25 Nov 2012 07:59:59 UTC +00:00,

My goal is to create a new variable, and convert the Time to a seconds integer. I tried with some methods like

seconds = offer_ends_at.to_time.to_i

I end up getting a epoc time. I'm after an actual integer that contains the amount of seconds left until the date happens.

最满意答案

我想要“一个包含到日期发生之前剩余的秒数的实际整数。”，然后你可以将你得到的时间戳减去当前的时间戳，即：

seconds = offer_ends_at.to_time.to_i - Time.now.to_i

I you want " an actual integer that contains the amount of seconds left until the date happens.", then you can substract the timestamp you're getting, to the current timestamp, ie :

seconds = offer_ends_at.to_time.to_i - Time.now.to_i
