In part because PostScript has better font technology, charts created using PostScript tend to have the best possible appearance. 14: THE TIME DIALOG The "Time Dialog" in the Settings menu opens a dialog box which provides many ways to set the time. Note that, because resetting the time in an astronomy program is so common a task, Guide provides several ways of doing it. For some purposes, you may prefer to use the "Enter Time" option described on page 30. Or you can make adjustments to the current time by clicking on the time shown in the legend, as described on page 3. You can access the Time dialog through the menu item in the Settings menu, or by clicking on the time shown in the legend. When you open this dialog, you will see something like the following. (The exact values depend on what your computer's built-in clock said when you started Guide). ++ + ++++ ++ ++ ++ 8 Aug 1985 12:03:31 -- - ---- -- -- -- Su Mo Tu We Th Fr Sa 28 29 30 31 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 1 2 3 4 5 6 7 Time Zone UTC JD 2446282.21078 Time Format Current Time Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec OK Cancel Right at the top is Guide's idea of what the time is. By clicking on a button above a figure, you can increment it; for example, each time you click above the '9' in 1985, you will go forward by a century. By clicking on a button below a digit, you can decrement it. If you only want to change a few figures a small amount and don't want to reach for the keyboard, this can be very convenient. (You can also click on the digits in the date/time shown in the Legend, without even needing to go to the Time dialog. Guide's title bar will change as the mouse goes over the digits, telling you what a mouse click on that digit will do.) If you click on the year, hour, minute and second fields on the second line you can just enter those values from the keyboard. This would, for example, be the fastest way to go from 1985 to -333.
