Changing the Date from UTC to Another Time Zone
I had some calculations that I wanted to do according to my app’s time zone and not UTC. Date.today was changing earlier than I wanted it to since the default is to use UTC. However, I found a simple way to fix this:
in application.rb:
config.time_zone = ‘Eastern Time (US & Canada)’
then you can use this to get the date in the time zone you set:
Time.current.to_date
If do not want to set the time_zone in the configuration, you can just do this:
Time.now.in_time_zone( ‘Eastern Time (US & Canada)’).to_date
Validations for Dates
I searched many times trying to figure out how to validate date of birth in my user model. Finally, I stumbled on the validates_timeliness gem and it worked great for validating if a user was old enough to join my site.
after installing the gem, i just added the line from the example in my user model:
validates_date :date_of_birth, :before => lambda { 18.years.ago },
:before_message => "must be at least 18 years old"

Thank you for making this gem available adzap!
