重修大明曆




《重修大明曆》是中国古代曆法，金朝赵知微制订。


天会五年（1127年），司天杨级造《大明历》，后来占候渐差，金世宗命司天监赵知微重修《大明历》，大定十一年（1171年）历成。赵知微重修在计算太阳运动中已经用到等间距三次差的内插法。又计算日食三限（初亏、食甚、复圆）中间已经用到的几何方法。《重修大明曆》从大定二十年（1180年）开始使用一直到元世祖至元十七年（1280年）被《授时曆》取代为止，正好使用了100年。


1太陽年=365.24359445日（歲實）、1朔望月=29.53059273日（朔策）。一近點月=29.55460929日，一交點月=27.21222500日。

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
