ElasticSearch: Get duration between two fields script syntax error

Question

I\'ve created this script in order to get a date difference between two fields:

use(groovy.time.TimeCategory) {
    def duration = doc[firstDateField].date -         


        

Answer 1

You can use another script that doesn't make use of the JODA Period class

Update your script file with this and that'll work:

(doc[secondDateField].date.millis - doc[firstDateField].date.millis) / 3600000
