In Selenium Java WebDriver, we can make use of GregorianCalendar(), Calendar.DAY_OF_MONTH, Calendar.MONTH, Calendar.YEAR, Calendar.SECOND,  Calendar.MINUTE and Calendar.HOUR to get Month, Day, Year, Second, Minute and Hour.

Sample Code:

int day, month, year;
int secnd, minute, hour;
GregorianCalendar date = new GregorianCalendar();

day = date.get( 
    Calendar.DAY_OF_MONTH
);
month = date.get( 
    Calendar.MONTH
);
year = date.get( 
    Calendar.YEAR
);

secnd = date.get( 
    Calendar.SECOND
);
minute = date.get( 
    Calendar.MINUTE
);
hour = date.get( 
    Calendar.HOUR
);

String todayDate = String.valueOf( month ) + 
    '/' + String.valueOf( day ) + 
    '/' + String.valueOf( year );
