z/OS Unix System Services allows definition of the offsets, but
not the boundaries. See:
http://www.twinsun.com/tz/tz-link.htm
I suppose z/OS eschews this technology in the name of POSIX
compatibility while mistaking an extension with an incompatibility.
z/VM? Enlighten me. Last I looked, if I performed a SENDFILE
the Friday before the DST change and received it the Monday after,
the restored time stamp was an hour off. Likewise the times
shown by the CP DISPLAY READER command. I suspect there are
Info APARs defining these behaviors as features.
Example: the file on the A drive was transmitted by SENDFILE last
week; it was RECEIVEd to the G drive a few minutes ago:
Cmd Filename Filetype Fm Format Lrecl Records Blocks Date Time
FTPXFER EXEC A2 V 71 68 1 11/03/10 14:10:27
FTPXFER EXEC G2 V 71 68 1 11/03/10 13:10:27
Does TSO TRANSMIT do any better?
