Ever seen the typical copyright message at the bottom of a website that's out of date? Yep. A surprising amount of websites have them!

Someone just hard coded the year and called it a day.
That's fine and dandy and it's not hard to change, but it's easy to forget you need to update it.
A better solution? Use Rails to dynamically generate it.
© <%= Date.current.year %> Your Company
This will always print the current year in your footer. We use
Date.current because we're using Rails and this method will take into account the current time zone in Rails.
You can also use
Date.today.year to use pure Ruby, but this won't apply the current time zone to the calculation.
Either way, this is will display the current year from the server side and will always be accurate.
