A malfunction of some Microsoft Corp Zune music players was caused by an error in the way the device accounts for leap years, Microsoft said.
In a statement on the Zune website posted late on Wednesday, the company blamed a bug in the internal clock driver related to the way the device handles a leap year, adding: The issue should be resolved over the next 24 hours as the time change moves to January 1, 2009.
The year 2008 had 366 days instead of the usual 365.
Early on Wednesday, thousands of users found they could not use the 30-gigabyte Zune model, made in 2006. Microsoft called the issue widespread, but said users could reconnect their players after 7 a.m. EST on Thursday.
