OutputWhat did you do?
I wrote a program that copies media files from one location to another and sets the ctime and mtime to the original file timestamp. The program copies a file and changes the date using
io.Copy(destFile, srcFile)
then callsos.Chtimes(dest, t.AccessTime(), t.ModTime())
to set the dates.What did you expect to see?
The dates to change to the dates provided... or an error at least. This silently fails.
What did you see instead?
It works appropriately in most cases, but when copying from a windows machine to a Linux SMB server the destination date is always set to
now
instead of changing to the src date.It works from Windows to Windows and from Mac to Mac. I haven't tried other combinations yet.
