对于存储在Access数据库的日期和时间类型字段中的日期，直接从数据库中读取数据的效果非常耗时，错新技术频道小编将和大家细细道来ASP常用日期格式化函数 FormatDate。
核心代码
<%'功能:多功能日期格式化函数'来源:http://jorkin.reallydo.com/article.asp?id=477Function FormatDate(sDateTime, sReallyDo) Dim sJorkin sJorkin = GetLocale() If Not IsDate(sDateTime) Then sDateTime = Now() sDateTime = CDate(sDateTime) Select Case UCase(sReallyDo & "") Case "0", "1", "2", "3", "4" FormatDate = FormatDateTime(sDateTime, sReallyDo) Case "00" FormatDate = FormatDate(sDateTime, "YYYY-MM-DD hh:mm:ss") Case "01" FormatDate = FormatDate(sDateTime, "YYYY年MM月DD日") Case "02" FormatDate = FormatDate(sDateTime, "YYYY-MM-DD") Case "03" FormatDate = FormatDate(sDateTime, "hh:mm:ss") Case "04" FormatDate = FormatDate(sDateTime, "hh:mm") Case "ISO8601", "GOOGLE", "SITEMAP" '//ISO8601格式, 一般用于GoogleSiteMap, "+08:00" 为时区.
