How to convert epoch to yyyy-mm-ddThh:mm:ss linux

Question

I want to convert epoch like "1444039517190" to yyyy-mm-ddThh:mm:ss using linux?

I have tried using the following script but it gives the wrong output:

echo 1444039517190 | awk '{ print strftime("%Y-%m-%d %H:%M:%S",$1) }'

Output:

47729-10-16 09:06:30

Answer 1

Your timestamp is not in seconds; try:

echo 1444039517190 | awk '{ print strftime("%Y-%m-%d %H:%M:%S",$1/1000) }'

Or if you don't mind losing precision:

date --date=@$((1444039517190 / 1000)) +%Y-%m-%d\ %H:%M:%S

And check if your version of strftime(3) support the shorter format %F %T instead of %Y-%m-%d %H:%M:%S.
