Class: Logger

Extensions to the built in Ruby logger.

If you want to use the default log formatter as defined in the Ruby core, then you will need to set the formatter for the logger as in:

  logger.formatter = Formatter.new

You can then specify the datetime format, for example:

  logger.datetime_format = "%Y-%m-%d"

Note: This logger is deprecated in favor of ActiveSupport::BufferedLogger

63:     formatter.datetime_format if formatter.respond_to?(:datetime_format)
64:   end

datetime_format=(datetime_format)
