    Function FormatDate(sDateTime, sReallyDo)

      FormatDate = FormatDate(sDateTime, "YYYY-MM-DD hh:mm:ss")

      FormatDate = FormatDate(sDateTime, "YYYY-MM-DDThh:mm:ss.000+08:00")
     Case "RFC822", "RSS", "FEED" '//RFC822格式, 一般用于RSS, "+0800" 为时区.
      SetLocale("en-gb")
      FormatDate = FormatDate(sDateTime, "ew, DD eMM YYYY hh:mm:ss +0800")

      FormatDate = Replace(FormatDate, "mm", Right("0" & Minute(sDateTime), 2))
      FormatDate = Replace(FormatDate, "ss", Right("0" & Second(sDateTime), 2))

      FormatDate = Replace(FormatDate, "m", Minute(sDateTime))
      FormatDate = Replace(FormatDate, "s", Second(sDateTime))
      If InStr(1, FormatDate, "EW", 1) > 0 Then
      SetLocale("en-gb")
      FormatDate = Replace(FormatDate, "EW", UCase(WeekdayName(Weekday(sDateTime), False)))
      FormatDate = Replace(FormatDate, "eW", WeekdayName(Weekday(sDateTime), False))

      FormatDate = Replace(FormatDate, "w", WeekdayName(Weekday(sDateTime), True))
      End If
      If InStr(1, FormatDate, "EMM", 1) > 0 Then
      SetLocale("en-gb")
      FormatDate = Replace(FormatDate, "EMM", MonthName(Month(sDateTime), False))
      FormatDate = Replace(FormatDate, "eMM", MonthName(Month(sDateTime), True))
      SetLocale(sJorkin)
      Else
      FormatDate = Replace(FormatDate, "MM", Right("0" & Month(sDateTime), 2))
      FormatDate = Replace(FormatDate, "M", Month(sDateTime))
      End If
     End Select
    End Function
    %>

用法如下：

<%
    '将日期格式化为ISO8601格式
    Response.Write(FormatDate("2008-03-06 08:03:06", "SITEMAP"))
    '将日期格式化为RFC822格式
    Response.Write(FormatDate("2008-03-06 08:03:06", "RSS"))
    '将日期格式化为(英星期, 英月/日/年)
    Response.Write(FormatDate(Now(), "eW, EMM/DD/YYYY"))
    '将生成一个以年月日时分秒随机数的字符串
    Response.Write(FormatDate(Now(), "RND"))
    %>
