I'm implementing a scim service provider for the free software 
Nextcloud, but I miss 2 informations for users:

  - created

  - lastModified

Reading rfc7643 it says that:

       created  The "DateTime" that the resource was added to the service
          provider.  This attribute MUST be a DateTime.

       lastModified  The most recent DateTime that the details of this
          resource were updated at the service provider.  If this
          resource has never been modified since its initial creation,
          the value MUST be the same as the value of "created".

I also read: https://datatracker.ietf.org/doc/html/rfc3339 but there is 
no option for a standard but null date.

Should I set it to year 0000, or to beginning of unix epoch?

(I also searched the ML, but the tool to search is really slow, couldn't 
really use it.)

Thanks for your help and have a nice day!
