Stylish atomic digital clock is packed with many features and offers modern look to add to your living room or kitchen. Outdoor temperature display receives wireless data from weather-resistant transmitting sensor within a 300 ft (91 M) range, down to -40 F. Large, 2 inch tall time digits set automatically to your time zone selection and adjust to daylight savings, all on an easy to read LCD with calendar display & moon phase. Clock indicates active alarm, WWVB signal, and low/weak battery with adjustable display language. Mount clock onto wall or fold-out leg stand to place on table. 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.
