Bug ID: 403127 Summary: Moving files across filesystems loses sub-second timestamp Product: dolphin Version: 18.12.1 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: dolphin-bugs-n...@kde.org Reporter: ad.liu....@gmail.com CC: elvis.angelac...@kde.org Target Milestone: --- SUMMARY In dolphin, when cut-and-paste a file from one filesystem to another, mtime is preserved to the second, but the sub-second part is zeroed out. STEPS TO REPRODUCE 1. ~ $ touch a ~ $ ls --full-time a -rw-r--r-- 1 jin users 0 2019-01-12 14:03:02.624385832 +0800 a ~ $ mv a /run/media/jin/sg10/data/ ~ $ ls --full-time /run/media/jin/sg10/data/a -rw-r--r-- 1 jin users 0 2019-01-12 14:03:02.624385832 +0800 /run/media/jin/sg10/data/a Above shows that both filesystems (ext4) support sub-second timestamp, and mv preserves it. 2. In dolphin, cut&paste /run/media/jin/sg10/data/a back to ~/ 3. ~ $ ls --full-time a OBSERVED RESULT ~ $ ls --full-time a -rw-r--r-- 1 jin users 0 2019-01-12 14:03:02.000000000 +0800 a EXPECTED RESULT ~ $ ls --full-time a -rw-r--r-- 1 jin users 0 2019-01-12 14:03:02.624385832 +0800 a SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.14.5 KDE Frameworks Version: 5.53.0 Qt Version: 5.12.0 ADDITIONAL INFORMATION -- You are receiving this mail because: You are watching all bug changes.
