在日常生活中，每天24小时的概念已经深入人心。实际上，这只是一个假设的数字，我们称它为平均太阳时间（mean solar time）或者是标准时间（universal time,ut.）。有了这个理论上的系统，人类便可以有规律地过日子。这个假设，成为心目中的真实。
　　其实，要是严格地计算百分之几秒，那一年365天中每天的长短都是不同的。记绿这种时间方式的系统，叫做真实太阳时间（real solar time）。每一天的长度计算，是太阳连续两次通过观察点最高之处之间的确实时间。或者用最简单的语言说，就是两次日照没有影子之间的那时间。一年中最短的一天，只有23小时44分钟；而最长的一天，则长达到达24小时14分钟，每天的长短，根据地球与太阳的距离而确定。与太阳的距离短，地球自转一天的时间就短，与太阳距离远，地球自转一天的时间就长。地球围绕着太阳转的一年轨迹，画在图上像一枚肾脏，其中只有四天与假设的圆周轨迹相交。如果三几秒忽略不计，那等于说，这四天我们可以真正地拥有24小时，它们是4月16日、6月14日，9月1日以及圣诞节。
　　在时钟尚未普及的日子里，真实太阳时间主导了我们的生活。中国人的“日出而作，日入而息”，是太阳时间的生活影响。而沿用日久晷，则是真实太阳时间的具体指示，日出日落，在日晷表面上留下了不同方位的影子。在瑞士巴赛尔的一家大教堂的外塥上，装设了一个巨型的日晷和一个同样大小的时钟。阳光普照时，可以清楚地看到两种时间的对比。对钟表有兴趣的人，看了当会发出会心微笑。
　　但在阴天，或者在晚上，日晷不灵光，真实太阳时间没有了意义，甚至无法得知当时的真实太阳时间。于是人们想出了办法，先计算出全年每天的真实太阳时间，再参考时钟指示的时间，得出当天的具体差异。这个时间判别数字，称之为时间差（equation of time）,计算公式是当天的有真实太阳时间减平均太阳时间（即24小时）。在本文的最后一段有一个俯表，列出全年的时间差，读者们可以据此计算每天的真实太阳时间。不过，以记忆下365个不同的数字，大概神童也未必优而为之。于是，人们就用复杂有机械把它在钟表上显示出来，避免大脑的操劳。最先将时间差功能装在袋表上的，是英国人苏利（henry sully）。不过，更精确更实用的装置是制表大师a.l 宝玑的发明。自18世纪末起，他和她的传人做了不少具备时间差装置的袋表，精确度以分钟为单位，成为给后人的珍贵遗产。今日，这些袋表在拍卖会不时可见到，成交价动机百万港元以上。
　　依照地球围绕太阳运行的轨迹，时间差装置的基本部分是一个肾脏形状的偏心轮，它的外缘附着与真实太阳时间指示运动的感应。一组四枚齿轮组成的传动序列，令偏心轮开始转动，每转一圈是365天5小时37分30秒（地球围绕着太阳转一圈即一年的真实时间）。
　　理论上，这样的设计是最理想的。但它复杂了，只能在口径大的袋表甚至时钟上装设。在腕表的有限空间内，这种方式根本无法使用。差不多10年前，宝玑的设计师想出了一组新设计，使时间差指示也能用在手表上。肾脏形偏心轮和日期输轮同步运动，哀减比率为1/12。这个高明的方式，完全没有影暗装置本身的精确度。万年历的日期轮在1461天（365 365 356 366）的周期里共转动48圈，而偏心输则配合着转4圈。换言之，在普通年份里增加的误差（每年责累小时37分钟30秒）会在闰年里得到补偿校正，如同闰年本身的宝际意义和存在价值一样。
　　今日，已经共有四五个品牌推出了时间差腕表。它的宝性，应该说已经得到肯定了。起码，这项功能会很对复杂腕表爱好者或收藏家的胃口。不过，现代作品中将时间差概念发挥得最淋漓尽致的，还是百达翡庇的袋表star caliber2000.它装有活动的真宝太阳时间分针，成为与太阳同步运动的精密机械。它可以指示出无须计算的即时间，还可以凭两枝同轴分针的距离指示出当天的时间差。谁都无法否认，这是时间艺术的又一次生华。希望，这一功能终于有一天在腕表上出现。
in daily life, the concept of 24 hours a day has taken root. in fact, this is just a hypothetical number, which we call the average solar time (mean) or standard time (universal time,ut.). with this theoretical system, humans can live on a regular manner. this hypothesis becomes true in the mind.
in fact, if you calculate a few seconds strictly, the daily length of the 365 days of the year is different. a system that remembers the time of green, called real solar time. the length of each day is calculated as the exact time between the sun's highest places through the observation point in a row. or in the simplest language, that is, two times the sun has no shadow between the time. the shortest day of the year, only 23 hour and 44 minutes, while the longest day, up to 24 hours and 14 minutes, the length of the day, according to the distance between the earth and the sun. the distance from the sun is short, the earth rotates a day for a short time, far from the sun, the earth rotates for a day longer. the earth's year-round trajectory around the sun is painted like a kidney, of which only four days intersect with the hypothetical circumference trajectory. if three seconds are ignored, it is tantamount to saying that these four days we can really have 24 hours, they are april 16, june 14, september 1 and christmas.
in the days when the clock was not yet universal, the real sun time dominated our lives. the chinese people's sunrise, the day into the interest,is the effect of the life of the sun time. and the use of daily sundial, is the real sun time of the specific instructions, sunrise and sunset, on the surface of the sundial left a different azimuth of the shadow. a giant sundial and a clock of the same size were installed on the outer 塥 of a cathedral in basel, switzerland. when the sun shines, you can clearly see the contrast between the two times. people who are interested in watches and clocks will smile when they see them. but on a cloudy day, or at night, the sundial is not bright, the real sun time has no meaning, even can not know the real sun time at that time. so people came up with a way to calculate the real sun time every day of the year, and then refer to the time indicated by the clock to arrive at the specific difference of the day. this time discrimination number, called the equation of time, is calculated as the day when there is a real solar period to reduce the average solar time (that is, 24 hours). in the last paragraph of this article there is a table that lists the time difference for the whole year, according to which readers can calculate the real sun times of the day. however, in memory of 365 different numbers, presumably the prodigy may not be excellent. as a result, people use complex and mechanical to show it on the clock, to avoid brain toil. the first to put the time difference feature on the bag table was henry sully, an englishman. however, a more precise and practical device is the invention of watchmaking master a.l breguet. since the end of 18th century, he and her heirs have made a number of bag watches with time-difference devices, with precision in minutes, which has become a precious legacy for future generations. todaythese bags are visible from time to time at auction, with a trading price of more than hk $ million. according to the trajectory of the earth's orbit around the sun, the basic part of the time difference device is a kidney-shaped eccentric wheel, whose outer edge is attached to the real solar time to indicate the movement of the induction. a set of four gears of the transmission sequence, so that the eccentric wheel began to turn, each turn is 365 days 5 hours 37 minutes 30 seconds (the earth around the sun circle, that is, the real time of the year).
in theory, such a design is ideal. but it is complex and can only be installed on large-caliber bag watches and even clocks. in the limited space of the watch, this method is simply not available. almost 10 years ago, breguet's designers came up with a new set of designs that allowed time-difference instructions to be used on watches as well. kidney-shaped eccentric wheel and date-transmission synchronous movement, the rate of mourning is 1/12. this clever way, completely without the accuracy of the shadow device itself. the date wheel of the perpetual calendar rotates 366 laps over a period of 1461 days (365 365 356 48), while the eccentric loss is matched by a turn of 4 laps. in other words, the increased error in the ordinary year (the annual 37分钟30秒 of responsibility) is compensated for in a leap year, just as the leap meaning and the value of existence are in years.
today, a total of four or five brands have launched time-difference watches. its treasure sex, should be said to have been affirmed. at the very least, this feature will be very appealing to complex watch enthusiasts or collectors. however, in modern works, the concept of time difference is most vividly played,it is also the bag table star caliber2000 of emerald. it is equipped with the active real treasure sun time minute needle, becoming a precision machine for synchronous movement with the sun. it can indicate the time that does not need to be calculated, and can also indicate the difference between the day and two with the distance of the coaxial minute hand. no one can deny that this is another birth of the art of time. hopefully, this feature will finally appear on the watch one day.
