We had those clocks in the Diplomatic Telecommunications stations around the world. Very accurate and never remember having to reset one, except when came in on night shift and some dodo had reset it for Daylight Idiot time. They were always on GMT (ZULU time). Thankfully they hadn't set the world wide computer time. Can you imagine the confusion work wide if that had happened?
