For people who store their appointments in Microsoft Outlook or other desktop-based calendar programs — rather than dynamic, Web-based programs such as Google Calendar — the situation gets trickier.
Patches for calendar programs are available, but appointments entered before a patch was applied might still be registered in standard time rather than daylight time — off by an hour.
Microsoft advises heavy calendar users to go online and download a small program known as "tzmove" — Time Zone Move — that can retrofit all previously booked appointments to the new daylight-saving rules. Other vendors offer similar tools for their systems.
Of course, it's likely not everyone would take that step, said Rich Kaplan, a Microsoft customer service vice president who oversaw the company's Y2K efforts and heads daylight-saving preparations. Hence Microsoft's advice to be cautious about meetings between March 11 and April 1.
"Because if one person applied the update, and one person didn't," he said, "you could end up there at the wrong time."
