How do I set a predefined time range?

I would like the time range to be a set "1 hour window". For example, if a customer selects 2pm, then I would like the "range" (next time field) to auto populate to 3pm. I want it to always force a set 1 hour window.

I'm afraid not, when using our Time field and enabling its Time Range, we cannot control automatically the ending time. it is designed to be selected manually by the user who fills out the form.

If the ending time will always be an hour after the starting time, I would recommend using an ordinary Text field, and writing this as a note on your form just under the field where they select the time.

The ending time that is 1 hour later cannot be automatically inserted into the field to show it to the user that way. Thank you.
