If you have a good desktop system, the last line in each individual entry of /usr/share/zoneinfo/ is the POSIX format; probably good for z/OS. E.g.: 547 $ tail -1 /usr/share/zoneinfo/America/Denver MST7MDT,M3.2.0,M11.1.0 Beware of: 548 $ tail -1 /usr/share/zoneinfo/Asia/Tel_Aviv IST-2IDT,M3.4.4/26,M10.5.0 Some older OSes don't support the "/26" modifier. Funny calendar there. And: 549 $ tail -1 /usr/share/zoneinfo/Europe/Dublin IST-1GMT0,M10.5.0,M3.5.0/1 Standard time in Summer; negative Daylight Saving in Winter! -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
