SWATCH Internet time? What is a Swatch .beat? We have divided up the day into 1000 .beats. So, one Swatch .Beat is equivalent to 1 Minute 26.4 Seconds. Why use Internet Time? Internet Time exists so that we do not have to think about timezones. For example, if a New York web-supporter makes a date for a chat with a cyber friend in Rome, they can simply agree to meet at an @ time - because internet time is the same all over the world. Where is the Internet Time meridian? Biel Meantime (BMT) is the universal reference for internet time. A day in internet time begins at midnight BMT (@000 Swatch .Beats) (Central European Wintertime). The Meridian is marked for all to see on the facade of the Swatch International headquarters on Jakob-Staempfli Street, Biel, Switzerland. When did Internet Time start? The BMT Meridian was inaugurated on October 23rd, 1998, in the presence of Nicholas Negroponte, founder and director of the media laboratory at the Massachusetts Institute of Technology. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of P S Sent: Tuesday, October 27, 2009 4:37 PM To: IBM-MAIN@bama.ua.edu Subject: Re: [IBM-MAIN] big iron mainframe vs. x86 servers On Tue, Oct 27, 2009 at 3:20 PM, McKown, John john.mck...@healthmarkets.com wrote: I don't like metric, personally.

With 20-20 hindsight, all computers should have started off marking files that way. It's not easy changing, but it would really be worth it. Regrettably, it rarely works right. MVS and UNIX early realized the benefit of UTC (but MVS only partly -- how are ISPF PDS members marked? What about tape labels?) But new systems must reinvent. MS DOS and Macintosh OS both well after started running the primary clock on civil time. Mac is better now; Windows is still ailing. I suspect the mechanism is that engineers eager to get to power-on test start their test beds with the clock on civil time. They procrastinate implementing the conversion routine. Then the shipment deadline looms, and the transition is deferred to a future release, then the conversion effort is unacceptable. (When will ISPF start using UTC?) And z/OS and Unix System Services still don't do it right for US timestamps prior to 2007. What fraction of z/OS installations (away from the UK meridian) still run the [E]TOD on civil time? Especially for those sites that gradually change the time to make sure transactions get stored in order as the clock bumps back because of daylight savings time - but also for any multi-time zone database. Gulp! And the ETR will only slew a couple seconds a day. It wouldn't finish before time to change back. I understand that during leap seconds, z/OS dispatches no jobs.

Re: big iron mainframe vs. x86 servers
The big advantages of the IBM mainframe architecture have always been application upward compatibility, I/O throughput, and RAS (reliability, availability, and serviceability). Application upgrade compatibility requires both hardware instruction set upward compatibility and software system interface upward compatibility. Intel has made some significant strides in recent years in terms of hardware instruction set upward compatibility, but Microsoft's software system interface upward compatibility is a joke. Windows release boundaries have been invariably disastrous, and service packs have been little better. I/O throughput on z System z processor complex is second to zone. No PC I/O architecture can come close to the throughput exhibited by a small System z processor complex. A large System z processor complex is in a universe all its own. IBM RAS (reliability, availability, and serviceability), developed and evolved over 45 years, is second to none, and RAS is what keeps businesses in business. For sheer number crunching, I might pick an IBM Power[n] box. If I want to go on the cheap, I might pick an Intel box. For transactional processing involving vast databases, anything other than a System z processor complex is irresponsible. Give that staggering number of financial transactions processed on a daily basis, over 90% of which is done on large-scale IBM mainframes, is it not strange that you have never heard of a mainframe virus? IBM RAS and IBM Security (whether implemented via IBM RACF, CA ACF/2, CA-Top Secret Security, or some other External Security manager (ESM)) is what keep these systems running. John P.

Re: big iron mainframe vs. x86 servers
I asked because the pretty slide show linked to by the original post I replied to used that number (1500) on the 13th and last slide with no indication of scale factor or context. After 48 yrs in IT I have an appreciation for the issues raised by the replies, both explicit and implicit. I was wondering from the practical point of view. Where is the cross-over point where one considers z10 vs squatty box? on power? on space? on software licences? admin bodies? is the issue to complicated without doing a full tca/tco? This was on my mind because I have the misfortune to have inherited support of a mainframe application connected to a squatty box using custom code and a token ring conenction to the mainframe. every time it burps i get indigestion. replacing it means using smtp to replace telephony -- swapping one poisonous snake for another breed.
