NoMethodError: undefined method `zone' for Time:Class

Question

How do i use Time.zone in ruby if I am not using rails I want to do Time.now but that's available in rails but not ruby

I thought that

require 'time'

would fix this and make it available in ruby but it didn't and I get

NoMethodError: undefined method `zone' for Time:Class

Answer 1

You've tried to use zone as if it were a class method (Time.zone) [1]. If you want to use a class method:

1.9.3-p448 :007 > Time.now.zone
=> "EDT" 

But Time.now is just a nice way of instantiating your own instance of Time[2]. So you're really just doing this (calling an instance method):

1.9.3-p448 :009 > time = Time.new
=> 2014-04-09 15:14:01 -0400 
1.9.3-p448 :010 > time.zone
=> "EDT"

Answer 2

I don't know, what do you mean. But I think it should work as below :

(arup~>~)$ pry --simple-prompt
>> Time.now
=> 2014-04-09 23:19:04 +0530
>> Time.now.strftime('%Z')
=> "IST"
>> Time.now.strftime('%z')
=> "+0530"
>> Time.now.zone
=> "IST"
