Unfortunately, A very important part of OpenGTS (Calendar) is not customizable! Although it's claimed to be an international opensource software.
However one can make opengts to support more calendar types by just using the icu4j components and replacing it's classes by that of java sdk (e.g. java.util.*) .
icu4j adds support for the following calendars out of box:
ChineseCalendar, CopticCalendar, EthiopicCalendar, GregorianCalendar, HebrewCalendar, IndianCalendar, IslamicCalendar .
As Shown Here: http://icu-project.org/apiref/icu4j/com/ibm/icu/util/Calendar.html
However others (like me!) can add further support for other calendars (e.g. PersianCalendar) by the use of other icu4j compliant libraries.
Like: http://sourceforge.net/projects/persiancalendar/
In addition to have a new DatePicker in Track.war pages, one need to customize the javascript (calendar.js) too!
