FIRST TIME I SEE THE 'TD'-EFFECT mentioned in a news paper article. The TD effect has been discussion last year on c.s.y2k; I have posted several newsgroup posts on this board. Only now it is appearing in a newspaper. John __________________ The phenomenon, known as the Crouch-Echlin Effect, was first observed last year by two software engineers and confirmed last week by Digital Equipment. It was widely discussed last week on Internet newsgroups and e-mail lists devoted to the Y2K problem. "The effect has the potential of causing such problems as randomly crashing your accounting system or, in the case of extreme system failures, causing a plant or factory to stop production," wrote Mike Echlin, one of the engineers who stumbled across the anomaly. The Crouch-Echlin Effect occurs in computers with an internal clock known as a "nonbuffered" Real Time Clock. The problem has been found most frequently in older 286, 386 and 486 computers, but has also been documented in some Pentium computers and embedded processing systems. THOSE MACHINES may handle the Y2K rollover just fine. But when they are turned off and on again, a glitch in the way the machine restarts itself can cause erroneous date and time settings to be sent to the computer's operating system. In one test, a computer set ahead to Jan. 9, 2000, for Y2K testing jumped to April 17, 2000, when restarted the following day. Any files worked on were saved with the date of April 17 rather than Jan. 10, generating miscalculations. Within two weeks, the computer believed it was December 2000. Several firms are now providing to utilities software that can find and repair the Crouch-Echlin problem. ...nj.com
