RSS PubDate Date Formatting Function

As you may already know, RSS feeds need to have their PubDate formatted properly to use. You may also know that most databases do not store a date in the same format as a RSS Data feed requires. This is a quick and easy way format your date into the required proper RSS PubDate.

The function is called RSSDate().
If you call RssDate("11/20/2008 12:44:29 PM")
It will output Thu, 20 Nov 2008 12:44:29 GMT

Here is the code for the RSSDate() function:

<%
      
Function RSSDate(TheDateTime)

   TheDay = Day(TheDateTime)
   DayName = WeekdayName(Weekday(TheDateTime),True)
   TheMonth = MonthName(Month(TheDateTime),True)
   TheYear = Year(TheDateTime)
   TheHour = Hour(TheDateTime)
   TheMinute = Minute(TheDateTime)
   TheSecond = Second(TheDateTime)

   While Len(TheDay) < 2
      TheDay = CStr("0" & TheDay)
   Wend
   While Len(TheHour) < 2
      TheHour = CStr("0" & TheHour)
   Wend
   While Len(TheMinute) < 2
      TheMinute = CStr("0" & TheMinute)
   Wend
   While Len(TheSecond) < 2
      TheSecond = CStr("0" & TheSecond)
   Wend

  RSSDate = DayName & ", " & _
            TheDay & " " & TheMonth & " " & TheYear & " " & _
            TheHour & ":" & TheMinute & ":" & TheSecond & " GMT"

End Function

Response.Write RSSDate("11/20/2008 12:44:29 PM")
