        "note": "A sundial reads local apparent (solar) time, but clocks run on a zone's reference meridian, so you add a longitude correction: 4 minutes of time per degree of longitude — correction = 4 × (reference meridian − local longitude), east positive. A dial at 7.5° E on Central European Time (15° E) reads 30 minutes slow versus the clock, so add 30 minutes. (For full clock time also apply the equation of time, which varies through the year.)",
