title: How to convert time stamp containing T and z ( for ex - 2020-03-02T16:30:36Z) to dd/mm/yyy hh:mm:ss
body: <p>I am designing a Flex dashboard. One of the column in my dashboard is a time stamp whose column contains entries like 2020-03-02T16:30:36Z. I want to convert it into dd/mm/yyy hh:mm:ss. Please help.
  I tried this but nothing happened. In-fact, the entries got removed from the flex dashboard
  df$time&lt;- as.POSIXct(df$time, 
  format="%Y-%m-%dT%H:%M:%OSZ", tz="GMT")</p>
