openssl ca works, but with error messages

[Robert Moskowitz]

I am using:

openssl ca -config $dir/openssl-root.cnf    -extensions v3_ca

With customizations in the cnf.

The command generates the cert to sign, but on doing that (or if I say 
N) throws the errors:

Certificate is to be certified until Jun  1 00:00:00 2024 GMT (385 days)
Sign the certificate? [y/n]:y

1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated

I am using specific dates:

default_startdate = $ENV::startdate
default_enddate   = $ENV::enddate

         Validity
             Not Before: May  1 00:00:00 2023 GMT
             Not After : Jun  1 00:00:00 2024 GMT

and it is getting the serial number

serial            = $dir/serial

         Serial Number:
             98:3f:27:9d:c7:3c:69:13

And why complaining about email_in_dn?

I do get the cert out, but why these errors and what should I be doing 
about them?

thanks
