Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/strptime. To experiment with that code, run bin/console for an interactive prompt.

TODO: Delete this and the text above, and describe your gem


Add this line to your application's Gemfile:

gem 'strptime'

And then execute:

$ bundle

Or install it yourself as:

$ gem install strptime


Strptime for time parsing

require 'strptime'
parser ='%Y-%m-%dT%H:%M:%S%z')
parser.exec('2015-12-25T12:34:56+09') #=> 2015-12-25 12:34:56 +09:00
parser.execi('2015-12-25T12:34:56+09') #=> 1451014496

Strftime for time formatting

require 'strptime'
now =
formatter ='%Y-%m-%dT%H:%M:%S.%L %z')
formatter.exec(now)        # 2017-12-29T07:24:31.505 +0900
formatter.execi(now.to_i)  # 2017-12-28T22:24:31.000 +0000
