On UN*X, st_ctime is the last status change time, not the creation time.
That's the time the file's inode last changed, so size changes, permission changes, etc. affect it. It's *not* the time the file was created; most UN*Xes don't provide that. Newer versions of FreeBSD, NetBSD, OpenBSD, and macOS do, but other UN*Xes don't appear to. On Windows, at least according to Microsoft's documentation, st_ctime *is* the creation time. Hopefully that's not the result of confusion on the part of somebody at Microsoft.
