VBScript Now 函数

VBScript Function Reference Manual

定义和用法

Now 函数可根据计算机系统的日期和时间设置返回当前的日期和时间。

语法

Now

提示和注释

重要事项：

如果同时读取 Date、Time 以及 Now，那么 Now = Date + Time，但是实际上，我们不可能同时调用这三个函数，因为执行完一个函数之后，才能执行另一个函数，所以如果您在程序中必需同时取得当时的日期和时间，必需调用 Now，再利用 DateVale 及 TimeValue 分别取出日期和时间。

Example: Obtain the date and time of a specific time point:

N = Now 'this time point's date and time
D = Datevalue(N) 'same time point's date part
T = TimeValue(N) 'same time point's time part
D2 = Date 'time point 1's date
T2 = Time 'time point 2's time

Problem Thinking

What is the maximum possible error value when executing Response.write Now and Response.Write Date + Time continuously? Assumption:

The Now obtained from 'time point 1' = #7/1/95 23:59:59#
The Date obtained from 'time point 2' = #7/1/95#

And if the 'time point 3' just crosses a day, then Time = #0:00:00, so the difference between Now and Date+Time becomes 23:59:59.

Instance

Example 1

document.write(Now)

Output:

2007-10-1 14:10:06

Note:The output results may vary slightly due to different computer settings.
