Date and Time Data Literals

This section provides rules on writing date and time literals, characters enclosed in hash signs. VBScript support several formats for the date string like ISO format and US format.

In the previous section, we learned that a date literal is a string representing a date and/or time enclosed in hash signs (#).

Here are some details about how to write a date and/or time literal:

Here is a tutorial example on how to write date and time in different formats:

<html>
<body>

<pre>
<script language="vbscript">
   document.writeln("#31-Dec-1999# = " & (#31-Dec-1999#))
   document.writeln("#21:26:00# = " & (#21:26:00#))
'   document.writeln("#21:26:00.123# = " & (#21:26:00.123#))
   document.writeln("#31-Dec-1999 21:26:00# = " _
      & (#31-Dec-1999 21:26:00#))

   document.writeln()
   document.writeln("ISO format:")
   document.writeln("#1999-12-31 21:26:00# = " _
      & (#1999-12-31 21:26:00#))

   document.writeln()
   document.writeln("US format:")
   document.writeln("#12/31/1999 9:26:00 PM# = " _
      & (#12/31/1999 9:26:00 PM#))
</script>
</pre>
</body>
</html>

Here is the output of the sample script:

#31-Dec-1999# = 12/31/1999
#21:26:00# = 9:26:00 PM
#31-Dec-1999 21:26:00# = 12/31/1999 9:26:00 PM

ISO format:
#1999-12-31 21:26:00# = 12/31/1999 9:26:00 PM

US format:
#12/31/1999 9:26:00 PM# = 12/31/1999 9:26:00 PM

Notice that the host environment is using the US format as the default format.
