Query: An excellent and accurate time keeper

After receiving this beautiful and accurate time keeping clock with its large numbers and clean face, I thought that "manually" meant that I could adjust it to Hawaiian Time manually. However, this work for awhile until the clock adjusted itself every 12 hours to the closest atomic analog time. For us in Hawaii, it is Pacific Time. Disappointed, I had to return it, but amazon.com gave me my full refund.
