Y2K again? Daylight time may baffle computers
Normally the switch to daylight-saving time isn't a big deal, but this Sunday, Jeff Ronner has to put people on the case.
Ronner is a San Francisco-area field services manager for technology outsourcer Perot Systems Corp., and he handles computer systems for a big Perot client, Catholic Healthcare West. This week he was putting final touches on his plan to make certain that Catholic HealthCare's voicemail systems and other networks recognize daylight time.
Those computers, like those of all but the most recent vintage, probably were programmed to believe that daylight-saving time begins the first Sunday in April and ends the final Sunday in October.
