Hi, I want to validate a time in odk form. How can I do?
What exactly do you mean by validate a time? Perhaps you can give an example of inputs your expect and how you'll know if they are valid or not?
For example, you have a question which you want to capture Starting time for doing survey. So I need to validate the question in order to capture the exactly time depending on the actual-time which is reading in the device. What can I do?
You don't need any additional question and validation in this case.
You can use metadata http://xlsform.org/en/#metadata there you can find
Additionally, if you need more values you can use our pretty new audit feature which logs times with each event: https://docs.opendatakit.org/form-audit-log/
A post was split to a new topic: How to use index-repeat within the repeating group
Is it possible to use mathematical inqualities to capture a valid time that is not exceeding or fall behind the required time for example this question"At what time do people in your household usually go indoors?"
