Displaying dates in Ditto
Ditto creates a [+date+] placeholder which can be connected to any date field in your document and used in the output template. The &dateSource and &dateFormat parameters make the connection between the date field and the placeholder.
&dateSource can be any date in the document properties, or a template variable that uses the Unixtime widget. The createdon field is the default date source.
Ditto only interprets dates in the form of a Unix timestamp, an integer repesenting the number of seconds that have passed since 1st January 1970. The Unix time when this page loaded was 1368992623. All built-in time-related properties are stored as timestamps. Template variables with type set to "date" are stored in a different (human-readable) format. You must set the template variable to use the Unixtime widget, which translates dates into a timestamp. If dates constantly come out as 1st Jan 1970, this usually means the input to Ditto is not a timestamp.
&dateFormat is a string that specifies date and time format, using the same definitions as PHP's strftime() function. Follow this link for the strftime() format specifiers.
Here are a couple of documents using my template variable pkDate:
And here are some using the createdon field with the time
