I have a list of creation time stamps and ending time stamps , i would like to get the amount of seconds last from creation to ending . could not find any way to do that without using UNIX time stamp (which i dont have at the moment) .
something like that :
datediff('second',min(creation_time),max(ending_time))
creation_time = '2017-03-20 10:55:00' ..
date_diff
date_diff('second', min(creation_time),max(ending_time))
