2 Overview of Date Functions Getting the current system date Getting the current system time Comparing dates Comparing times

3 Getting the Current System Date The DateString function returns the date of the computer as set in the system's control panel. So for example txtTheDate.Text = DateString Would display the current date in a text box called txtTheDate.

4 Getting the Current System Time The TimeString function returns the time of the computer as set in the system's control panel So for example txtTheTime.Text = TimeString Would display the current time in a text box called txtTheTime.

5 The Date Data Type An example of comparing dates…

6 Now The value of Now incorporates both the Date and the Time! So the following is a valid example of data returned by Now... 31/1/2005 11:19:23 Consider the following code... Dim MyDate As Date MyDate = Now lblMessage.Text = MyDate.Date Assuming the above value of Now, what value will be displayed in the control lblMessage?

7 Comparing Times Simple time comparisons are not a problem as follows...

8 Identifying a specific time Now.TimeOfDay, produces results like… 15:00:34.1093750 But does an alarm clock need to be so precise?
