解决办法
Do not cycle through the questions.
Do not manually adjust the times.
Set the dateTime question as readOnly. This means the dateTime questions record the system value when added. However, this time cannot be adjusted.
Complete the survey in a web browser. Draft mode can be enabled if the survey needs to be completed in a remote environment.
