This Ruby code snippet demonstrates how to get the current date in the ISO 8601 format using the Time class and the strftime method. The strftime method takes a string argument that specifies the format of the output, and %F is a special code that represents the full date in the ISO 8601 format (YYYY-MM-DD).

The code first creates a new instance of the Time class using the now method. This method returns the current time as a Time object.

Then, it uses the strftime method to get the current date in the ISO 8601 format. The %F code is used to specify that the output should be formatted as YYYY-MM-DD.

Here is an example of how this code might be used:

t = Time.now
puts t.strftime("%F") # Output: 2023-01-15

In this example, the current date (January 15, 2023) is printed to the console in the ISO 8601 format.

Ruby code snippet

t = Time.now
#=> 2025-06-27 15:34:16.991110734 +0000
t.strftime("%F")
#=> "2025-06-27"
