我爱星币 10:56 2005年3月18日 (CST) Changing the date and time

When SkyMap starts running, it automatically reads the time and date from the computer's clock, and draws a map for that time. To display a map for a different time, click the Bm17.png button on the "Set View" toolbar to display the Observation Time Dialog:

改变日期和时间

当SkyMap开始运行时,程序会自动读取系统日期和时间,显示当时的星图。显示非当前时间的星图,点击“设置”工具栏的Bm17.png 按钮,显示观测时间对话框

Set the desired time and date, then click the OK button to display the map for the new time. If daylight saving time is in force on the selected date, check the Daylight saving time box; otherwise, make sure that it is unchecked. If the time has been changed previously, and you want to display a map for the current time and date, click the Now button; this sets the time and date to the values read from the computer's clock. To set the time to midnight, click the Midnight button. This sets the time to 00:00:00 while leaving the date unchanged. Note that midnight is taken to be the start of the day, not the end of the day.

设置你需要的日期和时间,点确定以刷新星图。如果采用夏令时,请把夏令时选框勾上,否则一定不要勾。如果时间已经流逝,想得到当前时间的星图,请点击现在,程序会从电脑时钟中读取系统时间。点击午夜会保留当前日期而将时间设为零点。这里把午夜视作一天之始而非一天之终。

Notes

  • If the "Set View" toolbar is not currently visible, use the View/Toolbars... menu item to switch it back on.
  • The time and date that you enter are always taken as "local mean time", and internally converted to UTC (Greenwich mean time) using the time zone information specified in the Observation Location Dialog. If you wish to enter times in UTC directly, this can be done by setting your time zone to zero in that dialog.
  • Dates on or after 15th October 1582 are considered to be in the Gregorian calendar. Dates before this are considered to be in the Julian calendar.
  • 如果“设置视场”工具栏不可见,在查看/工具栏中将其选中。
  • 输入的日期和时间将视作“当地时”,程序会参照观测站位置对话框中的信息在内部转化为世界时(格林尼治时间)。如果想直接输入世界时,请在该对话框中将时区设为零。
  • 1582年10月15日及之后的日期将视作格里历日期,之前日期将视作儒略历日期。
