title: about pm2 reloadLogs and log-date-format
body: <p>I am using pm2 version 0.12.9</p>
  
  <p>I start a app using command:</p>
  
  <p><code>pm2 start bin/www --name gototravel --log-date-format="YYYY-MM-DD HH:mm Z"</code></p>
  
  <p>then I query the pm2 logs</p>
  
  <p><code>ll ~/.pm2/logs</code></p>
  
  <p><code>-rw-rw-r-- 1 wucho wucho    0 May 12 11:03 gototravel-error-0.log</code></p>
  
  <p><code>-rw-rw-r-- 1 wucho wucho 1822 May 12 11:03 gototravel-out-0.log</code></p>
  
  <p>my first question is I don't see log file prefixed with a timestamp.</p>
  
  <p>then I run </p>
  
  <p><code>pm2 reloadLogs</code></p>
  
  <p>and query the pm2 logs,but no another log is generated</p>
  
  <p><code>ll ~/.pm2/logs</code></p>
  
  <p><code>-rw-rw-r-- 1 wucho wucho    0 May 12 11:03 gototravel-error-0.log</code></p>
  
  <p><code>-rw-rw-r-- 1 wucho wucho 1822 May 12 11:03 gototravel-out-0.log</code></p>
  
  <p>I am a nodejs newbee , could you give me any suggestions?</p>
