Subject: Re: Logger datetime_format not respected

My fault, copied the wrong version:

require 'logger'
log = Logger.new(STDOUT)
log.datetime_format = "%Y-%m-%d %H:%M:%S"
log.formatter = proc { |severity, datetime, progname, msg|
    "[#{datetime}] #{msg}\n"
  }
log.info "#{log.datetime_format}"

outputs:

[Wed Mar 03 15:01:05 -0700 2010] %Y-%m-%d %H:%M:%S
