addDays

public StiDateTime addDays(double value)

Returns the DateTime resulting from adding a fractional number of days to this DateTime. The result is computed by rounding the fractional number of days given by value to the nearest millisecond, and adding that interval to this DateTime. The value argument is permitted to be negative.

Parameters:

value -

Returns:

addHours

public StiDateTime addHours(double value)

Returns the DateTime resulting from adding a fractional number of hours to this DateTime. The result is computed by rounding the fractional number of hours given by value to the nearest millisecond, and adding that interval to this DateTime. The value argument is permitted to be negative.

Parameters:

value -

Returns:

addMilliseconds

public StiDateTime addMilliseconds(double value)

Returns the DateTime resulting from the given number of milliseconds to this DateTime. The result is computed by rounding the number of milliseconds given by value to the nearest integer, and adding that interval to this DateTime. The value argument is permitted to be negative.

Parameters:

value -

Returns:

addMinutes

public StiDateTime addMinutes(double value)

Returns the DateTime resulting from adding a fractional number of minutes to this DateTime. The result is computed by rounding the fractional number of minutes given by value to the nearest millisecond, and adding that interval to this DateTime. The value argument is permitted to be negative.

Parameters:

value -

Returns:

addMonths

public StiDateTime addMonths(int months)

Returns the DateTime resulting from adding the given number of months to this DateTime. The result is computed by incrementing (or decrementing) the year and month parts of this DateTime by months months, and, if required, adjusting the day part of the resulting date downwards to the last day of the resulting month in the resulting year. The time-of-day part of the result is the same as the time-of-day part of this DateTime. In more precise terms, considering this DateTime to be of the form y / m / d + t, where y is the year, m is the month, d is the day, and t is the time-of-day, the result is y1 / m1 / d1 + t, where y1 and m1 are computed by adding months months to y and m, and d1 is the largest value less than or equal to d that denotes a valid day in month m1 of year y1.

Parameters:

months -

Returns:

addSeconds

public StiDateTime addSeconds(double value)

Returns the DateTime resulting from adding a fractional number of seconds to this DateTime. The result is computed by rounding the fractional number of seconds given by value to the nearest millisecond, and adding that interval to this DateTime. The value argument is permitted to be negative.

Parameters:

value -

Returns:

addYears

public StiDateTime addYears(int value)

Returns the DateTime resulting from adding the given number of years to this DateTime. The result is computed by incrementing (or decrementing) the year part of this DateTime by value years. If the month and day of this DateTime is 2/29, and if the resulting year is not a leap year, the month and day of the resulting DateTime becomes 2/28. Otherwise, the month, day, and time-of-day parts of the result are the same as those of this DateTime.

Parameters:

value -

Returns:

daysInMonth

public static int daysInMonth(int year,
                              int month)

Returns the number of days in the month given by the year and month arguments.

Parameters:

year -

month -

Returns:

isLeapYear

public static boolean isLeapYear(int year)

Checks whether a given year is a leap year. This method returns true if year is a leap year, or false if not.

Parameters:

year -

Returns:
