boy ... do I goof !! I think this be a atomic clock . turn out all it do be reset itself from regular time to daylight savings etc. . not what I need . I want one that reset after the power go out ... or if you move it from spot to spot . I really do think it be self setting ... sorry . I would have give he no star if that be a option . how in the world can a `` atomic '' clock be so wrong ! sorry for yell . . but this be beyond ridiculi . it be actually 14 minute fast ... and as mention by someone earlier there be no way to make correction . what a waste . complaint # 2 be that ... if someone need big number so as to see they wothout glass ... it might also follow that they hearing be not as sharp as it once be . the alarm ??? on this thing be not as loud as mant of the bird outside my window each morning . I be hopeful this review will help someone make a different choice when purchase from this company .
