About this edition:
Time is precious and should not be wasted even in seconds as Allah has made an oath upon time in the Noble Quran: “By the time” (Surah Asr). People have measured time since many thousand years with various means to achieve its use & accuracy. Today, Man can measure time precisely with an error of one second in a billionth year. This edition sheds light on history, working principles and significance of timekeeping devices.
