title: Add timestamp and username to log
body: <p>I have setup Logging inside my settings.py, and I want to know if it's possible to add to the error log line - Which user experienced the error and a timestamp for the issue. Is this possible?</p>
  
  <p>Current code</p>
  
  <pre><code>LOGGING = {
      'version': 1,
      'disable_existing_loggers': False,
      'handlers': {
          'file': {
              'level': 'DEBUG',
              'class': 'logging.FileHandler',
              'filename': 'debug.log',
          },
      },
      'loggers': {
          'django': {
              'handlers': ['file'],
              'level': 'DEBUG',
              'propagate': True,
          },
      },
  }
  </code></pre>
