我如何安排时间?
原标题:How would I format a time string?

载于I ve got:00:03:30.877615

时间、分钟和秒钟。

我想要做的是,格式与:3:30相同。

我基本上需要几分钟(没有头零)和整秒钟。

扼杀大多数都是一样的,但 de脏场所的长度可能会改变。

最佳回答

这里有两种选择。 如果你知道你的开端,那么你可以做一个简单的 transform变:

start_time =  00:03:30.877615 
mins_and_secs = start_time[3..7]
mins_and_secs = mins_and_secs[1..-1] if mins_and_secs[0] ==  0 

这将是最快的选择。 如果你重新预计会有更多的改动,你实际上可以创建,然后使用#strftime

问题回答

“-”在会议记录中位列第一。

>> require  time 
=> []
>> t = Time.parse( 00:03:30.877615 )
=> 2012-01-12 00:03:30 -0800
>> t.strftime("%-m:%S")
=> "1:30"

你们能否依靠这一时间格式? 如果是的话,我就只能使用一种定期的表述,并删除我想要的东西:

reg = /dd:(dd):(dd).*/
if m = reg.match(s)
  "#{ m[1].to_i }:#{ m[2] }"
end
