La Crosse Technology 513-1419BL-INT Backlight Atomic Full Calendar Clock with Extra Large Digits - Perfect Gift for the Elderly
Easy to read, day or night, this wall clock makes a perfect gift. Time digits measure close to 2 1/2 inches tall and day of the week is 1 inch and features a nighttime backlight. Clock is lightweight made of durable plastic, and is simple to operate. Includes AC adapter or requires 2 AA batteries (not included) and keeps your time accurately set according any one of 7 us time zone settings. Low power indicator icon lets you know when batteries will need changing. There is an error in the DST ON/OFF mode setting. All States except Arizona must set the DST mode to OFF.
Due to a software omission, if the NIST adds a leap second (https://en.wikipedia.org/wiki/Leap_second) in December, your clock will be one hour fast during the month and will resume to normal time January. If this happens, you can correct the time by setting the DST mode to OFF for the Month of December. Then turn DST mode back ON in January.
For correction of December time error, see below corrective action in the description
