how to calculate uptime as java expression [message #698607]

Hi there, i am working on a report in BIRT where i need to calculate uptime as below in BIRT.
Up time= number of days per month X 23 X 60
I would like to have this calculation in one of computed columns as java expression and as number of days in a month change, formula should calculate accordingly.

i.e Up time for june = 30 * 23 * 60
uptime for July = 31 * 23 * 60

can you please assist to create this logic as java expression in BIRT?

Thanks in advance.

Can you try an expression like:

importPackage(Packages.java.util);
cal = new GregorianCalendar();
cal.setTime(new Date());
days = cal.getActualMaximum(Calendar.DAY_OF_MONTH);
days*23*60;
