Ruby: How to define a datetime field in YAML?

In YAML, you can define a datetime field using the ISO 8601 format, which is widely supported and recommended for datetime representations. Here's how you can define a datetime field in YAML:

datetime_field: 2024-06-10T12:30:45Z

In this example:

  • datetime_field is the key representing your datetime field.
  • 2024-06-10T12:30:45Z is the value representing the datetime. It consists of the date (YYYY-MM-DD), followed by the time (HH:MM:SS), and optionally the timezone (Z for UTC, or ±HH:MM for a specific timezone offset).

You can replace datetime_field with your desired key and 2024-06-10T12:30:45Z with your specific datetime value.

When loading this YAML into Ruby, you can parse the datetime string into a DateTime object using the DateTime.parse method:

require 'yaml' require 'date' yaml_data = <<~YAML datetime_field: 2024-06-10T12:30:45Z YAML data = YAML.load(yaml_data) datetime = DateTime.parse(data['datetime_field']) puts datetime # Output: 2024-06-10T12:30:45+00:00

This will parse the datetime string into a DateTime object, which you can then use in your Ruby code.
