Hi,

I have a date value:  
@timestamp: 2024-04-01T12:08:00:548Z

I want to use the scripted field / runtime field option to creat a new field based on the logic below:

IF @timestamp \>= 10 minutes  
Then  
ten\_minute\_breach = “yes”  
else “no”

Finding it difficult to get this working

Any advice or help  
Thanks!

hi @ek9boy

where is the `@timestamp` value stored?  
I'm asking this as runtime field painless can only access document level information, unless hardcoded in the script itself.
