By last weekend, the Red Cross IT staff had completed updates for its Blackberry and e-mail servers, she said, finishing up two important cogs in the DST process.

During the time change early Sunday, the Red Cross plans to have extra IT workers available to handle any problems. Extra staffers will be on hand afterward, as well, to deal with any issues that pop up later.

The changeover this weekend doesn't end the agency's work. The Red Cross also created a mobilization plan to help it deal with the change back to standard time that will occur on Nov. 4. "It will be a regular IT item for us to track for future DST changes. A lot of the challenges we found this time are not going to be there" in November, she said.
