When setting default values for the CLONED record…can we set a date-time field with a future date?

Yes. You can set the date-time field of the newly cloned record with a default value.

– To enter a static date… use format: mm/dd/yyyy
– To enter a dynamic date… use tokens like: {{today}}+n where n could be any integer (e.g. {{today}}; {{today}}+5; {{today}}-1). These tokens output will be a date.
