This is the same end timestamp expressed as a numeric, epoch/millisecond-style, value rather than a formatted date-time string. This numeric form exists for programmatic consumers, such as scripts or monitoring integrations, that need to do arithmetic on timestamps, like computing exact run duration in milliseconds, without parsing the human-readable DateAndTime string. A value such as '1785823800000' would represent the same completion moment as the formatted EndTs value, but ready for direct numeric comparison in automation.
