Szia Gábor, Thank you very much for the explanation! Good to know there's no serious problem or misunderstanding here, but a conscious algorithmic choice being fooled by clock skew. I wonder if there's a way such clock skew can appear without actual committer clocks being off by months... > FWIW, much work is being done on a cached commit graph including commit > generation numbers, which will solve this issue both correctly and more > efficiently. Perhaps it will already be included in the next release. Wonderful news, thanks for sharing it! -- Regards, Feri
