Usage

From source file:Main.java

/**
 * Subtract one positive Duration from another, larger positive Duration.
 * @param d1 The larger positive duration
 * @param d2 The smaller positive duration
 * @return The difference/*from  w  ww.  ja  va2s  . c  o m*/
 */
private static Duration subtractSmallerPositiveDurationFromLargerPositiveDuration(Duration d1, Duration d2) {
    BigDecimal s1 = fractionalSeconds(d1);
    BigDecimal s2 = fractionalSeconds(d2);
    BigDecimal extraSeconds = s1.subtract(s2);

    Duration strip1 = stripFractionalSeconds(d1);
    Duration strip2 = stripFractionalSeconds(d2);

    Duration stripResult = strip1.subtract(strip2);

    if (extraSeconds.compareTo(BigDecimal.ZERO) < 0) {
        stripResult = stripResult.subtract(DURATION_1_SECOND);
        extraSeconds = extraSeconds.add(BigDecimal.ONE);
    }

    BigDecimal properSeconds = BigDecimal.valueOf(stripResult.getSeconds()).add(extraSeconds);

    return FACTORY.newDuration(true, BigInteger.valueOf(stripResult.getYears()),
