How do I set the time zone? It run out of battery so when I changed it, the time zone is pacific and I need to change it to mountain time.

To change the time zone, open the control compartment cover on the bottom of the clock. Locate the "Time Zone" switch and set it to the appropriate time zone for your area. Six time zones are programmed into your clock, "A" for Atlantic, "E" for Eastern, "C" for Central, "M" for Mountain, "P" for Pacific and "H" for Hawaiian. Once you've chosen the correct time zone for your Brookstone digital desk clock, you must select whether you want the clock to operate using the 12-hour or 24-hour format. The clock is set to the 12-hour format by default. If you'd like to change the setting to the 24-hour format, locate the "Time Format" switch on the bottom of the clock and flip it to "24-hour".
You can also decide whether to turn your clock's automatic Daylight Savings Time feature on or off. If you turn the feature on, your clock will automatically move forward by one hour at 2:00 a.m. on the first Sunday in March and fall back by one hour at 2:00 a.m. on the first Sunday in November. To choose your preference, locate the "DST" switch on the bottom of the clock and flip it to "Auto" or "Off".
