I believe you have just register the domain and very eager to see the registration in the whois list. The normal time require for appearing the domain in the whois directory is 48 hours after registration.
Normally, most of the registrars update their databases immediately to give enough faith to their clients, you can also get email from the registrar about the registration of domain in whois directory. If you query the registrar's database directly, you will probably see your registration for that domain name.
