Thank you for the quick reply.

You have to store the timestamp after validating the date with something like the following in the date validator:

[‘myDate’, ‘date’, ‘timestampAttribute’ => ‘myDate’],

where I will put this code

['myDate', 'date', 'timestampAttribute' => 'myDate']

I think it works now.

I tried @qiang suggested.

Thank you.
