How to convert epoch time to human

[Darthmouth]

Hello friends,

I want a UNIX function where i want to convert epoch column into to date the form (DD / MM / YYYY HH24: MI: SS). For example if my input is epoch ==> 1264712387 Input: epoch ==> 1264712387 then my output has to be as 28/01/201 0 20:59:47 output : 28/01/201 0 20:59:47 . Does anyone know how to do it.

If you want to convert epoch time to human then i would suggest you to use the following code, hope you get some idea from here

cat file |while read EPOCH
do
READABLE=`gawk 'BEGIN{print strftime("%c", $EPOCH )}'` 
READABLE=`gawk 'BEGIN{print strftime("%c",123456)}'` 
echo $READABLE
done

I have one question can you tell me why did you use loop when gawk can get the whole thing without the loop

READABLE=$(gawk '{print strftime("%c", $0)}')
echo $READABLE

and if you want you can convert epoch seconds to whatever time format you want by using the below code

#!/usr/bin/ksh93

while read EPOCH
do
   printf "%T\n" '#'${EPOCH}
done < file

Till my knowledge if you want to convert from epoch UTC to human readable time, then you need to find the number difference between DateTime class' base time to epoch time. After that you need to multiply your epoch time by the tick resolution and then add your base ticks. Now finally you have to pass the ticks into the DateTime constructor and get a nice human-readable result
