Extracting time from @timestamp field using Runtime

[stephenb (Stephen Brown)]

Yes HH:mm:ss is what im looking for

So you need to look at examples here...

Using Datetime in Painless | Painless Scripting Language [8.11] | Elastic

And the API Here...

• java.time
• java.time.chrono
• java.time.format
• java.time.temporal
• java.time.zone

OK we can do that as a keyword... filtering and sorting you will need to see if that works... You will need to figure out the timezone stuff if you want to...

ZonedDateTime zdt = doc['@timestamp'].value;
String datetime = zdt.format(DateTimeFormatter.ISO_LOCAL_TIME);
emit(datetime);
