Thanks All. Yes, I tried DateTime() and ZopeTime() separately in a dtml method like: <dtml-var expr=_.DateTime()> <dtml-var expr=ZopeTime()> It returns same value. But when I use the Zopetime() in my database ZSQL method, like <dtml-sqlvar expr=ZopeTime() type="string">, it will give error messages:"Attribute Error: ZopeTime Attribute" But when I change to: <dtml-sqlvar expr=_.DateTime() type="string">, It works well. I just feel confusion. Any way, thansk so much for all your suggestion. yan __________________________________ Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95 per month! http://sbc.yahoo.com
