9. Press SET/WAVE button to enter DST MODE

The DOWN button toggles between DST ON and OFF
The UP button toggles the time zones as Eastern, Central, Mountain, Pacific, AK-Alaska, HI Hawaii until your desired time zone shown on display.

1. Press SET/WAVE button to enter LANGUAGE MODE

Holding down either + or - button change the language to EN (English or your common language).

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".

Late to the party I guess. Lots of entries for setting the clock, but not for the alarm. Press the plus or minus button. That's it. After you have the time set, you can then press the ALARM button above the WAVE/SET button to turn it on.

Slide the Wake 1/Wake2/Clock switch to the Clock position. Then press the forward button to advance the clock by the needed amount of time. Then slide the switch back to the side with the key icon.

If you set the DST switch to ON, you can move the time zone switch to one time zone further east for a few weeks until the DST change in the program takes effect. Then move the time zone switch back to your current time zone. (Repeat this in the fall to correct for the later change in DST again). The exact length of time between when DST starts and ends versus when the clock will change the program will depend on when the clock was manufactured. Clocks built after July 2006 should have the correct DST programs. Clocks from earlier have a much shorter period of DST (April through Oct).

I hope this helps.

The MTG-900 supports automatic DST which can be activated in the time setting mode.  However, the ROM in the MTG-900 dates from before Congress (in their infinite ability to make mistakes) modified the DST schedule, so, instead of switching at the beginning of April and the end of October (as currently specified), it switches at the end of April and the beginning of October (as previously specified).
I do not believe that there is a way to change the DST scheduling or manually turn DST on or off.  I've resorted to changing the time zone manually and turning off the DST feature.  IOW, I set the timezone to Pacific (LAX) during PST, and, to Mountain (DEN) during PDT.

Using the Emerson CKD5809C manual (also with SmartSet(tm) ), try Zone 4. TIME ZONE button: "04".

Zone 1: Atlantic Time
Zone 2: Easter Time (Default)
Zone 3: Central Time
Zone 4: Mountain Time
Zone 5: Pacific Time
Zone 6: Yukon Time
Zone 7: Hawaiian Time

As for disabling the Daylight Saving Time (DST) time change I have some guesses to try (not having one of these radios in my hand) or just skip to #4 below.
1. Manually setting the time and see if this disables the DST change.
2. Is there a Zone setting other than above? Like maybe a Zone 0? And then manually set the time.
3. Look at http://www.fixya.com/support/t236208-daylight_savings_time_adjustment for my solution there and try adjusting the DST Start to the same as DST End or DST Start and End with a month of 0 (if that is possible).
4. Or for the really desperate, change the Zone to 5 during DST and back to 4 during standard time (no worst off than with no DST auto setting.) (After I wrote this, I found an Emerson reference to no DST areas, Saskatchewan in this case, in the CKS1850C manual http://www.emersonelectronics.ca/emerson/en/product/details/2383, pg 9, and this is their solution.)

Appparently the problem could be with your location, or just that there may be a delay before time correction until the old date - check again the link to amazon i posted before - there are a couple of new reviews that discusss the daylight saving issue, also - The US clock says; "I have a radio controlled clock that receives NIST time. Will the new rules affect me? Your radio controlled clock should automatically implement the new DST rules. The WWVB broadcast contains information that tells your clock whether DST or ST is currently in effect. NIST always sends this information to agree with the current DST rules, so your clock should change automatically on the day of the change, just as it has in previous years. If the time is wrong after the DST change, make sure that your clock has recently received the time signal. Many radio controlled clocks have a synchronization indicator that will tell you if your clock has recently synchronized. If the clock isn't receiving the signal, click here for some tips on improving reception. If it has received the signal recently, check to make sure that the clock's time zone setting is set properly. Also, if you live in an area where DST is not observed (Arizona, for example), you need to disable the automatic DST function on your clock. I have a non-radio controlled clock that used to automatically correct itself for DST. Will it still work? The only way to find out is to wait and see, or to contact the manufacturer of the clock. There are a large number of non-radio controlled clocks, marketed under names like "AUTOSET" or "SMARTSET" that have internal firmware that automatically changes the time by one hour on the transition days to and from DST. These clocks do not connect to a NIST time service, and some of them will no longer work properly due to the DST rule change. For example, clocks manufactured prior to the rule change will probably not switch to DST in March, but will wait until April in accordance with the old rule. If you have a clock like this that fails due to the new rules, your only recourse is to adjust the clock manually, or to contact the manufacturer and ask for an upgrade or a replacement. If you need to contact manufacturer check http://www.emersonscott.com/ezsetamclocr.html Hope this helps:)
