Tim Harford made two mistakes in the Oct. 28 "Undercover Economist," about daylight-saving time. First, the article originally implied that Arizona was in the Pacific time zone during daylight-saving time. Though it keeps the same time as the Pacific states, Arizona officially remains in the Mountain time zone during daylight time. Second, the article reversed the schedule for daylight time. It occurs in the summer months, not in the winter months.

In the Oct. 26 "Gaming" column, Stefan Fatsis incorrectly stated that 57 tiles were unseen when Michael Cresta exchanged two tiles in hopes of drawing a T and a Y.

The correct probability is 1 in 513.
