WTF!?  And why?  I hadn't noticed that.  Is it because it's easier to
count lines if RECFM=FB (count bytes and divide by LRECL)?  Or
because revision level is/isn't available as the last two characters
of the sequence numbers (shouldn't matter).  Is this documented?

Does NFS have the same behavior?  I'll need to test.  I know that
"touch" via NFS fails to update the time stamp.  Can the programmer
enable/disable stats with NFS?

If the data originate from a z/OS (or CMS) system, it might be
better to use TRANSMIT (SENDFILE)/RECEIVE.  If you want to
copy to/from a UNIX (etc.) system and replicate timestamps,
you're probably SOL.

(TRANSMIT/RECEIVE may have a 1-hour skew if  a Daylight
Saving boundary (or the Equator) is between.  They could
have done better.)
