  <p>I would like a time stamp per log message ie</p>

  <p>here is my log4j config file</p>
  
  <pre><code>log4j.rootLogger=debug, stdout, R
  
  log4j.appender.stdout=org.apache.log4j.ConsoleAppender
  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
  
  # Pattern to output the caller's file name and line number.
  log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
  
  log4j.appender.R=org.apache.log4j.RollingFileAppender
  log4j.appender.R.File=c:\\development\\DCMail\\logs\\digestlogfolder\\digest-logfile.log
  
  log4j.appender.R.MaxFileSize=100KB
  # Keep one backup file
  log4j.appender.R.MaxBackupIndex=1
  
  log4j.appender.R.layout=org.apache.log4j.PatternLayout
  log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n 
  </code></pre>
