The formatting can be done like this (I assumed you meant HH:MM instead of HH:SS, but it's easy to change):

格式可以这样做(我以为你指的是HH:MM而不是HH:SS，但是很容易修改):

Time.now.strftime("%d/%m/%Y %H:%M")
#=> "14/09/2011 14:09"

Updated for the shifting:

更新后的变化:

d = DateTime.now
d.strftime("%d/%m/%Y %H:%M")
#=> "11/06/2017 18:11"
d.next_month.strftime("%d/%m/%Y %H:%M")
#=> "11/07/2017 18:11"

You need to require 'date' for this btw.

顺便说一句，你需要为此要求“日期”。

#2

require 'date'

current_time = DateTime.now

current_time.strftime "%d/%m/%Y %H:%M"
# => "14/09/2011 17:02"

current_time.next_month.strftime "%d/%m/%Y %H:%M"
# => "14/10/2011 17:02"

#3

time = Time.now.to_s

time = DateTime.parse(time).strftime("%d/%m/%Y %H:%M")

for increment decrement month use << >> operators

对于递增递减月，使用< >>操作符

examples

例子

datetime_month_before = DateTime.parse(time) << 1



datetime_month_before = DateTime.now << 1

For date:

日期:

#!/usr/bin/ruby -w

date = Time.new
#set 'date' equal to the current date/time. 

date = date.day.to_s + "/" + date.month.to_s + "/" + date.year.to_s
#Without this it will output 2015-01-10 11:33:05 +0000; this formats it to display DD/MM/YYYY

puts date
#output the date

The above will display, for example, 10/01/15

上面将显示，例如，10/01/15

And for time

和时间

time = Time.new
#set 'time' equal to the current time. 

time = time.hour.to_s + ":" + time.min.to_s
#Without this it will output 2015-01-10 11:33:05 +0000; this formats it to display hour and           minute

puts time
#output the time

The above will display, for example, 11:33

上面将显示，例如，11:33

Then to put it together, add to the end:

然后把它们放在一起，加到最后:

puts date + " " + time
