It appears that NFS attempts to create and display NFS timestamps.
But, on Solaris, with a PDS mounted from z/OS, I see:

ISPF shows resolution no finer than one minute. NFS shows nanoseconds.
The only entry for which NFS agrees with ISPF is the newest one. (I
suspect that might be cached. But where?) For all other entries, NFS
shows timestamps distributed over about one second about a month ago.
I suspect the newer ones were changed by NFS; the others by other means
(FTP, OMVS "cp", ISPF Edit, ...). The Changed dates ISPF shows are
plausible; I haven't logs to confirm.
What's happening here?
(Would this be better asked on ISPF-L or MVS-OE?)
