From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

FWIW, the stat structure in Linux does not include birth time [1]. It only gives you:
atime: The time of last access.mtime: The time of last modification.ctime: The time of the last change to the inode.I assume the
statcommand is using a filesystem-specific method to get the birth time.Anyway, I don't think any of these stats is guaranteed to be consistent with the rest (or even correct). For example, it is common to disable
atimetracking to improve I/O performance.Assuming the data is accurate, I think the other comment about the file being a copy is the best explanation.
The
statcommand is using statx, which gives you a slightly different struct. statx is the cool new Linux-only system call for stat-ing. Not every filesystem will support the new btime field. (And, as you correctly say, many of those time fields are wrong, anyway)Ooo neat. I was not aware of this syscall. TIL!
