Specifies whether to suppress the date/time information included in a special comment inserted automatically at the beginning of every generated HTML file, which looks as the following:
<!-- Generated by DocFlex/XML RE 1.8.5 on Tue Jul 05 15:03:12 CEST 2011 -->
When this option is selected (true), such a comment is still inserted, however without the current date/time:
<!-- Generated by DocFlex/XML RE 1.8.5 -->
Note: Besides affecting the automatic HTML comment, this option is also passed to templates via 'output.noTimeStamp' property available in FlexQuery expressions. So, if a template is programmed to display the generation's date/time on some page, it may suppress that as well, according to the setting of this option.

You may want to avoid getting the current date/time into the generated doc files, when you frequently upload them to some repository, which stores only changes of files against their previous versions. If your docs actually do not change, this will prevent the repository from storing unnecessary information.
NOTE: For commercial template applications developed by Filigris Works (e.g. DocFlex/XML XSDDoc), this option will work only in the presence of a commercial or trial license covering the given template application.
