What it means
Rows with an end time earlier than their start time were rejected.
What to do: Check the source’s clocks.
Trace one reversed interval
An illustrative row with start 10:30 and end 10:15 has an end before its start on the same date and clock basis. The Engine rejects that interval. Turning its difference into an absolute value would hide the reason for the rejection.
Check the source clocks and mapping
Review the original start and end fields, dates, time zones and source clock behaviour. Confirm that field_map has not exchanged the start and end columns. Repair the export or declaration only when the source evidence supports that repair.
Revalidate and inspect the affected interval again. If the timestamps remain contradictory, retain that limitation rather than interpreting the rejected row as zero work or a corrected positive duration.
