On 2020-06-17 i imported a revocation cert to my keyring. The key is revoked BUT the timestamp shows the date the Revocation-Cert was created instead of the date it was imported/applied!
In consideraton that gpg auto-generates a Revocation-Certificate right after Keypair-Generation and you apply that Revocation-Certificate eg. 10 years later, it still suggests that the key was revoked right after the Key-Pair was generated.
If possible gpg should display the date the Revocation-Cert was applied instead of the date it was created.
