No. One of the rules for a new block is that its timestamp is greater than the previous block's.

This applies to all blocks in the canonical chain. I believe uncle blocks may have the same timestamp, since their contents are not part of the canonical chain.

  • I read this from someone else too, could you provide a source on this? I was browsing earlier today and saw someone's geth allowing same timestamps in different blocks github.com/ethereum/go-ethereum/issues/….

  • The link you provided discusses this. It is a part of the ethash consensus rules, but other consensus engines like clique don't necessarily have the same constraints.
