The list of methods to do TimeUnit Calculate are organized into topic(s).

Method

longgetDateDiff(Date date1, Date date2, TimeUnit timeUnit)
Get a diff between two dates 
long diffInMillies = date2.getTime() - date1.getTime();
return timeUnit.convert(diffInMillies, TimeUnit.MILLISECONDS);
longgetDateDiff(final Date d1, final Date d2, final TimeUnit timeUnit)
Calculates the difference between 2 date objects and returns the result in the requested time units. 
long differenceInMilliseconds = d2.getTime() - d1.getTime();
return timeUnit.convert(differenceInMilliseconds, TimeUnit.MILLISECONDS);
longgetDifference(Calendar initDate, Calendar endDate, TimeUnit units)
get Difference 
return units.convert(endDate.getTimeInMillis() - initDate.getTimeInMillis(), TimeUnit.MILLISECONDS);
LoadingCachegetExpiringMap(long time, TimeUnit unit)
get Expiring Map 
return (LoadingCache<T, V>) CacheBuilder.newBuilder().concurrencyLevel(1).expireAfterWrite(time, unit)
        .build(new CacheLoader() {
            public Object load(Object key) {
                throw new RuntimeException();
        });
longgetFragment(final Calendar calendar, final int fragment, final TimeUnit unit)
Gets a Calendar fragment for any unit. 
if (calendar == null) {
    throw new IllegalArgumentException("The date must not be null");
long result = 0;
int offset = (unit == TimeUnit.DAYS) ? 0 : 1;
switch (fragment) {
case Calendar.YEAR:
    result += unit.convert(calendar.get(Calendar.DAY_OF_YEAR) - offset, TimeUnit.DAYS);
...
DategetFutureDate(long delay, TimeUnit timeUnit)
get Future Date 
if (delay > 0) {
    return new Date(new Date().getTime() + TimeUnit.MILLISECONDS.convert(delay, timeUnit));
} else {
    return new Date();
longgetInterval(final Date startDate, final Date endDate, final TimeUnit timeUnit)
get Interval 
long durationMills = endDate.getTime() - startDate.getTime();
return millisecondsTo(durationMills, timeUnit);
StringgetIntervalInfo(long intervalDuration, TimeUnit unit)
get Interval Info 
TimeUnit[] timeUnits = TimeUnit.values();
long[] values = new long[timeUnits.length];
for (int i = 0; i < values.length; i++) {
    values[i] = (i == unit.ordinal()) ? intervalDuration : 0;
for (int i = 0; i < timeUnits.length - 1; i++) {
    long value = values[i];
    long nexUnitValue = timeUnits[i].convert(1, timeUnits[i + 1]);
...
longgetMilliseconds(int interval, TimeUnit unit)
get Milliseconds 
long millisPerUnit = 1;
switch (unit) {
case DAYS:
    millisPerUnit = DateTimeConstants.MILLIS_PER_DAY;
    break;
case HOURS:
    millisPerUnit = DateTimeConstants.MILLIS_PER_HOUR;
    break;
...
longgetNowTimeUnit(TimeUnit timeUnit)
Get the current time in the specified time unit. 
switch (timeUnit) {
case NANOSECONDS:
    return TimeUnit.MILLISECONDS.toNanos(System.currentTimeMillis());
case MICROSECONDS:
    return TimeUnit.MILLISECONDS.toMicros(System.currentTimeMillis());
case MILLISECONDS:
    return TimeUnit.MILLISECONDS.toMillis(System.currentTimeMillis());
case SECONDS:
