?? I'm not concerned about local file copies. I'm talking about transferring files between systems via sftp.
When the target system is Solaris or AIX, mtime is not modified. When the target is either of my SuSE 9.1 systems, mtime is modified.
If foo_bar_foo's premise is absolutely true, then I should get the same behavior regardless of the *nix flavor I am using, but that is not what I am seeing.
Is there a way to configure behavior of mtime when using sftp? I sure don't see anything obvious in the config files...
