Hi,

I am using ELK GA 5.0.0. I have a time entry like `06:52:02` and a delay entry (in seconds) like `1.016`. I want to push another attribure to elasticsearch, by subtracting seconds from timefield, say `06:52:01` in this case. Is this possible?

Thank you.

With a ruby filter you could.

I don't know ruby, but if you have a search through the posts here you will find similar threads with examples.

Neither do I know ruby 😞

It will be really helpful if someone like @magnusbaeck or @theuntergeek or @Christian_Dahlqvist look into it

Please don't ping other people like that, if you aren't willing to do a search and spend some time, why would they provide you a direct answer?  
We do like to help, but you need to help yourself as well.
