太陽の位置により方位を知ることのできる時計です。太陽のマークがついている短針を太陽の方向に向けます It is a clock that can know the direction by the position of the sun. Point the hour hand towards the sun. 北半球では時計の短針を太陽に向け12時の位置との中間が南を指します In the Northern Hemisphere, the hour hand of the clock faces the sun and the middle of the 12 o'clock position points south. 南半球では時計の12時を太陽に向け短針との中間が北を指します In the Southern Hemisphere, clock 12 o'clock facing the sun, halfway to the hour hand points north 磁石が指す磁北と真北には誤差があります。このコンパスは真北を指す設定です。磁北から見た真北の差が偏角です There is an error between magnetic north and true north indicated by the magnet. This compass points to true north. The difference between true north as seen from magnetic north is declination. 地球の動きは太陽に対し一定では無いため均時差が発生します。南中時刻は、2月は14分位遅く、11月は16分位早くなります Since the movement of the earth is not constant with respect to the sun, an equation of time will occur. Mid-South time is about 14 minutes late in February and 16 minutes early in November. 例えば、日本の時刻は東経135度に合わせているので正午に太陽が真南に来るのは明石市付近です。東経135度以外の地域では1度につき4分の差が出ます For example, the time of Japan is adjusted to 135 degrees east longitude, so the sun comes to the south at noon near Akashi. In areas other than 135 ° E, there will be a 4 minute difference per degree. 方角がわかっているときは、針を方角に合わせることにより太陽の位置を知る事ができます(逆引き) When the direction is known, you can know the position of the sun by setting the needle to the direction. 利用のためには位置情報の使用の許可が必要です Permission to use location information is required for use
