自远古利用日影的圭表和日晷起，中间经汉、隋、唐、宋等朝代，附装在水力天文仪器上的水力天文钟，都采用了齿轮和凸轮的传动，即已都属于机械性。元代郭守敬以后，到明初的詹希元，更发展到独立时钟机构，並有了指针和表盘。可是近四百年，即自明代万历年间，西洋的自鸣钟传来我国，我国在计时器方面的工作，始终在模制阶段，自己的发明遂归于停顿。那次会议闭幕以后，会中曾用英文出版一次，我国1956年12月，《天文学报》4卷2期用中文出版一次。现在根据一些新资料，重新加以增删和改正。

Additionally, the hinge will point north, and the diptych will be angled so the gnomon is parallel to the Earth's axis of rotation. At solar noon, sunrise and sunset, the latitude adjustment of the diptych can't affect the time of either sundial, but at 9am and 3pm, each degree of latitude error (from holding the sundial at the wrong angle) creates four minutes of difference between the two faces.

另外，当绞链朝向北方，摺叠式日晷被旋转了一个角度，晷针才能与地球的自转轴平行，则当正午、日出与日落时，摺叠式日晷的时间不会受到纬度改变的影响，但是在早上9点和下午3点，纬度每偏差1度，在两个晷面上的时间便会相差4分钟(肇因於日晷在错误的纬度上)。
