Date validation

Hello everybody !!!

What is the problem? Please be detailed.
My problem is to create a validation to activate a question after a specific date.

Example after xx-xx-xx date you can see the question p1, and that can not be answered before that date in specific.

What ODK tool and version are you using? And on what device and operating system version?
ODK XLSForm v1.7.0
ODK Collect v1.19.0
Windows 10 / Android

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.
This is the validation in Spanish

Thank you all

Hola @Over_Murillo_Chacon,

Considera usar en relevant decimal-date-time(today()) > decimal-date-time('2019-03-31') .
Documentacion ODK de funciones de fecha / hora
