How do I convert epoch time to Normal time

[mshaik39]

In File monitoring extension(source: GitHub), the metric named as "last modified time" is returning time in an epoch format. So, how do we convert that epoch time to Normal time format?

Hi

While taking last modified time (file watcher) metric in dashboard it is showing epoch time format. How can I convert that epoch time in normal readable form (dd\mm\yyyy hh:mm:ss). I've tried using metric expression but it was not working, also when I'm using format string (time range ${t}) it is showing as "Last 1 day". 

Kindly help me to solve this issue, thank you in advance.
