Centracomm said that it was initially concerned about the impact of the daylight savings time change on security event correlation tools that it uses, but has since then received patches from the necessary vendors, as well as infrastructure vendors it depends on like Juniper Networks. Centracomm is ready to go for the DST change, as are the systems it manages for its customers, he said.

But over at Ce De Candy, in Union, N.J., Daylight Savings Time may result in the burning of some midnight oil before Sunday, said IT manager Rick DePinto.

"It's a big pain in the neck," said DePinto, who said changes to the company's payroll system and a matrix of Microsoft patches still need to be implemented.

Ce De pays its workers hourly and bases the time worked on a time clock system that takes the information from the clocks and uploads the data to the program on a PC, which in turn uploads it to the ERP system on the back end.

"All of these time-related payroll issues have to adjust when daylight savings goes into effect," said DePinto. Unfortunately the instructions Ce De got from the payroll vendor are not clear on what needs to be done. "We've been spending a lot of man hours on this," DePinto said.
