title: Add current time before log message
body: <p>I created a custom logger for my application, called CRON_LOG, just by adding this piece of code to config/environment.rb</p>
  
  <pre><code>CRON_LOG = Logger.new("#{Rails.root}/log/cron.log")
  CRON_LOG.level = Logger::INFO
  </code></pre>
  
  <p>And then, when I want to log something, just do that:</p>
  
  <pre><code>CRON_LOG.info "something"
  </code></pre>
  
  <p>It works fine, but I'd like to add the current timestamp before each log message. Of course I can just add <code>Time.now</code> to my log message, but I'd like to know if there is a way to add it as default to every log message. How can I do that ?</p>
  
  <p>Thanks.</p>
