column is nlinks.) Many files are OK. Those with mtime=0 date back to before commit e4752118691e41ae8307649d1abfd4739b3e4bfa. Those with mtime=-3599 typically have a lot of hard links (for deduplication) and correspond to source files that rarely change, which suggests they might have been created long ago and we’re just seeing now the symptoms of old problems. Actually, the wrong mtime may come from the synchronization of the store on the new storage device on berlin a couple of months ago. That sounds very likely. I was not able to reproduce on my machine using ‘guix copy --from’ (which uses the same code path as offloading) so I’ll just close it assuming it’s a problem specific to berlin. Ludo’.
