  <p>To change the time zone, i had followed as commented at <a href="https://github.com/Unitech/pm2/issues/560" rel="nofollow">https://github.com/Unitech/pm2/issues/560</a></p>
  
  <p>But it does not work. The behavior is the same as thought the "TZ" is not present. I tried even hard coding the time zone to numeric value like "+08:00" which does not work. How to change the time zone in the logs.</p>
