IEDR have updated their whois output to include the domain name registration date.
The whois output now includes both the registration and the expiry dates.

Several other ccTLDs do not publish registration or expiry data in whois to avoid exposing registrants to scams such as “domain slamming”, so it comes as a surprise that IEDR would have made this change without notifying registrars in advance.
