"We made it just fine through the daylight-saving time transition and the world hasn't ended," Sally Dahl, vice-president of customer and seller operations for Chicago-based uBid.com, said in an e-mail. "At this point, we have no reports of any system or application issues."

Dahl's company attributed much of the success of its DST preparations to the upfront patching and maintenance work done by IT services company, Rimini Street Inc., which provides support for applications from Siebel Systems Inc. and Oracle Corp.'s PeopleSoft and JD Edwards divisions. Rimini is based in Las Vegas.

Seth Ravin, president and CEO of Rimini Street, said in an e-mail early today that his company's "support lines have been quiet so far with no reported DST issues from our clients.

"It is still early, but so far, we are having the 'nonevent' we worked with our clients to achieve," he said. "We will continue standing by to assist clients as necessary with our 24x7 support, but expect a quiet Sunday on the emergency support lines."

Over the last few months, hardware and software vendors have been releasing a myriad of patches and software updates to head off potential DST problems. The time change, which used to take place on the first weekend in April, began at 2 a.m. today -- early this year because of changes in federal law aimed at energy savings.
