Time_format_change_procedure

Hi Guys, I am trying to create a use-case as " date when any single user was created in AD" it's done but I need to change time format to readable format, right now it coming like this "20170905133223.0Z" how can I convert it to as " 05-September-2017" I tried with eval command as follows but no effect in results. search:| ldapsearch domain=default search="(objectClass=user)" | table displayName,whenCreated |eval epochtime=strptime(whenCreated, "%Y %m %d %H:%M:%S") | eval desired_time=strftime(epochtime, "%d/%m/%Y") result: ABC|20170905133223.0Z **desired result:** ABC|05-September-2017
