The taskjuggler_utils package offers tools that will provide nice reports (taskjuggler-report), gantt charts (taskjuggler-gantt) and time shift the whole taskjuggler project file (taskjuggler-timeshift).
The best thing is that you don't need to use Graphical User Interfaces for that, so these can be automated from cron jobs, web servers and makefiles.
Reports are generated using LaTeX syntax since I use them in my LaTeX files easily, but we can easily add code to generate HTML reports as well in future.
