Kettle does not support the parsing of ISO-8601
date formats, which is Splunk's format for passing date objects through web services.
However, you can edit the date string returned from Splunk using the Modified Java Script Value step. Use this script to parse the
date:
var dateobj = str2date((substr(_time, 0, 23) + "GMT" + substr(_time, 23)).trim(), "yyyy-MM-dd'T'HH:mm:ss.SSSz");
