Hello -

I would like to create a scripted field that takes my existing timestamp field and subtracts 1 hour.

What I have is:

timestamp\_OMi  
Language: painless  
Type: date  
Format: Date  
Script: doc['@timestamp'].value - 3600000

When this is in place I receive a "Courier Fetch... shards failed" error.

Thanks for your help,  
Butch

You need to use `.getMillis()` to get the date in milliseconds:

`doc['@timestamp'].value.getMillis() - 3600000`
