If true, indicates that the generated output does not include the current date/time as part of a special comment inserted automatically at the beginning of every generated HTML or RTF file.

In HTML, that comment looks like the following:

<!-- Generated by DocFlex/XML RE 1.8.5 on Tue Jul 05 15:03:12 CEST 2011 -->
In RTF, it is:
{\comment Generated by DocFlex/XML RE 1.8.5 on Tue Jul 05 15:03:12 CEST 2011}
Using "Suppress timestamp" output format option (available for both formats), the user may request to exclude the date/time from such comments, which will be indicated by this property.

If a template is programmed to display the generation's date/time on some page, this property may be checked to suppress that as well, so the current date/time will be excluded from the generated doc files altogether.
