Global variable not changing value of time in 2 different functions

I'm running this code and it show the same time but i wanted different dates so i put the sleep so it would change the time in 10 seconds.

But is not changing @date_format

 r=Time.now  
 @date_format =  r

def self.asd 
puts  @date_format
 sleep 10
end

def self.asd1  
 puts @date_format
end

How can i do something like this?

If you want the time to change, you have to assign Time.now everytime. What you have inside @date_format is the returned value, not the method.

This should work:

def self.asd 
puts  Time.now
 sleep 10
end

def self.asd1  
 puts Time.now
end

Edit

Posible solution to your question on the comments:

class Test
   @date_format

   def self.date_format
     @date_format = Time.now
   end
   def self.date_format=value
     @date_format = value
   end
end

You can use it then, like this: Test.date_format and everytime you call that method, you'll get the new time and it'll update the variable.

Let me know if that helps.

Here is one approach that may work for you:

>> @date_format = lambda { Time.now }
=> #<Proc:0x007fdaa4800b98@(irb):5 (lambda)>
>> @date_format.call
=> 2011-12-21 11:20:35 -0500
>> @date_format.call
=> 2011-12-21 11:20:39 -0500

Hope it helps!
