Certificates usually have an expiration date relative to the certification date. A new formatter method should allow calculating such a relative date in the certificate generation process.
Note: this is only available when generating certificates using the phantomjs method, it is not possible to do dynamic calculations in the PDF-Forms method.
- Implement a formatter method with the option to add a relative date information (days, month, years)
- Make the formatter available in the phantomjs velocity context during certificate generation
- Add info about how to use this to manual
