The published application Date.today could get the local time in the development environment, but when it was published, it was in UTC time.
What I did
Change the default time zone to Japan time
As a result, although it is registered as UTC time in the database, it is displayed as the time of Tokyo in the application (I think you can see that it was UTC+9:00).
As a method to get today’s date Change from Date.today to Time.zone.today
By default, it is registered in UTC time in the database, and it is often changed to the local date and time using Time.zone, so remember this method.
