How to Convert epoch time to human readable format?

bugnet
Path Finder

Hi everyone,

I have the following event:

"... src=218.2.3.256 act=block app=ips rt=1433065461040 ...."
The rt field is a epoch computer time format.

Is it possible to convert the "rt" field to a user-friendly format? I searched through some of the other questions but none really addressed this specific question.

Thanks.

You can use the eval function strftime

... | eval formatted_time=strftime(rt/1000, "%H:%M:%S %d-%m-%Y")

Does not work for me .
The "formatted_time" always displayed with the same value : 23:59:59 31-12-9999

Convert your epoch time from millis to seconds

... | eval formatted_time=strftime(rt/1000, "%H:%M:%S %d-%m-%Y")

you need to do a field transform at search or index time - http://docs.splunk.com/Documentation/Splunk/6.3.3/Knowledge/Managefieldtransforms

Looks good. How I can do it for all variations of the "rt" numbers?
