To display the date using VBScript, you use the VBScript date() function.
date()

VBScript Date Code
To display this to the user, you need to output it like you would anything else - for example, using the document.write() method.
document.write(date())

Or even better, you could put the date into a variable first, then output the variable:

localDate = date()
document.write(localDate)

VBScript Date Format
You can use the VBScript FormatDateTime() method to format the date to either a long date format or a short date format.

The FormatDateTime() method accepts two arguments:
The date being formatted, and the required format (indicated by a constant). The formats are specified as follows:
0 - This represents the default date format (as in the previous example)
1 - This represents the long date format (based on the user's regional settings)
2 - This represents the short date format (based on the user's regional settings)

Long Format
To use long date format, you pass the FormatDateTime() an argument of 1.
localDate = FormatDateTime(date(), 1)
document.write(localDate)

Short Format
To use long date format, you pass the FormatDateTime() an argument of 2.
localDate = FormatDateTime(date(), 2)
document.write(localDate)
