RE: [Zope] DateTime adding not working

I want a date that is 14 days after today, and I tried <!--#var expr="ZopeTime + 14"--> and I get a bad operand error.

The source says that you can "a positive or negative number and a date-time object may be added to obtain a new date-time object that is the given number of days later..."

Try "ZopeTime() + 14"
