comment What exactly is inside a private key?
This question appears to be off-topic because it is about using openssl and the format it uses, rather than about the cryptographic keys themselves. It would be on-topic on Unix & Linux.

comment Why use a timestamp and how can someone know it's the correct one?
@rath I disagree: this is a question about why one would design a cryptographic protocol in a certain way. It's on-topic here, and a bit too theoretical for Information Security.

comment In RSA, why is it important choosing e so that it is coprime to φ(n)?
$e=65537$ also requires a good padding scheme. It makes some of the attacks against badly padded RSA harder but not all of them.
