How to Prevent duplicate values in the Date and time field?

Question / Problem

How do I prevent duplicate values in the Date and time field or Time field?

Is there a native feature in Kintone to prevent users from inputting the same values in an App?

Yes, there is @Jayron_Rosel ~

An easy way to prevent users from entering the same values in a Kintone App is to use the Prohibit duplicate values setting.
