推荐答案

您可以在应用程序的开头将 Date.Now 的值保存在全局变量中：

You can save the value of Date.Now at the start of your application in a global variable:

Public StartDate As Date = Date.Now

然后可以计算当前日期在任意时间范围内，使用在此代码中任意时刻从该起始日期和当前日期计算出的 TimeSpan ：

Then you can calculate the current date in your arbitrary time scale, using the TimeSpan calculated from this starting date and the current date, at any point in your code:

Dim Elapsed As TimeSpan = Date.Now - StartDate
Dim NewDate As Date = ArbitraryStartDate + Elapsed

选择 ArbitraryStartDate 是您想要的带有 Date 构造函数，如

Choose ArbitraryStartDate to be any date you like with the Date constructor like

Dim ArbitraryStartDate As Date = New Date(1983, 05, 03)
