Join Kevin Skoglund for an in-depth discussion in this video Date and time helpers, part of Ruby on Rails 4 Essential Training.
…Rails offers many tools to assist us with date and time…calculations as well as formatting of dates and times for output.…These methods aren't exactly helper methods…like the other ones we've been looking…at, because these methods are available throughout Rails, not just in the views.…These methods are additions that Rails make to Ruby's core classes.…Because they're available anywhere the rails console is a…great place for you to try them out and experiment.…Let's get an overview of what methods are available.…First, we can call methods on integers in…order to assist us with date and time calculations.…
So, for example we have second, minute, hour, day, week, month and year.…And you can call those on an integer to get…the number of seconds that would make up that item.…So 30.days would return the number of seconds that make up thirty days.…That's useful when we have a calculation, because…we can do time.now plus 30.days minus 23.minutes, and…it will return a date time to us…that's been changed by the appropriate number of seconds.…
