public static final long currentTimeMillis()
Gets the current time in milliseconds. By default this returnsSystem.currentTimeMillis()
. This may be changed using other methods in this class.
- Returns:
- the current time in milliseconds from 1970-01-01T00:00:00Z
public static final Chronology getChronology(Chronology chrono)
Gets the chronology handling null. If the chronology isnull
,ISOChronology.getInstance()
will be returned. Otherwise, the chronology is returned.
- Parameters:
chrono
- the chronology to use, null means ISO in the default zone
- Returns:
- the chronology, never null
public static final long getDurationMillis(ReadableDuration duration)
Gets the millisecond duration from the specified duration object handling null. If the duration object isnull
, zero will be returned. Otherwise, the millis from the object are returned.
- Parameters:
duration
- the duration to examine, null means zero
- Returns:
- the duration in milliseconds
public static final Chronology getInstantChronology(ReadableInstant instant)
Gets the chronology from the specified instant object handling null. If the instant object isnull
, or the instant's chronology isnull
,ISOChronology.getInstance()
will be returned. Otherwise, the chronology from the object is returned.
- Parameters:
instant
- the instant to examine, null means ISO in the default zone
- Returns:
- the chronology, never null
public static final long getInstantMillis(ReadableInstant instant)
Gets the millisecond instant from the specified instant object handling null. If the instant object isnull
, thecurrentTimeMillis()
will be returned. Otherwise, the millis from the object are returned.
- Parameters:
instant
- the instant to examine, null means now
- Returns:
- the time in milliseconds from 1970-01-01T00:00:00Z
public static final Chronology getIntervalChronology(ReadableInstant start, ReadableInstant end)
Gets the chronology from the specified instant based interval handling null. The chronology is obtained from the start if that is not null, or from the end if the start is null. The result is additionally checked, and if still null thenISOChronology.getInstance()
will be returned.
- Parameters:
start
- the instant to examine and use as the primary source of the chronologyend
- the instant to examine and use as the secondary source of the chronology
- Returns:
- the chronology, never null
public static final Chronology getIntervalChronology(ReadableInterval interval)
Gets the chronology from the specified interval object handling null. If the interval object isnull
, or the interval's chronology isnull
,ISOChronology.getInstance()
will be returned. Otherwise, the chronology from the object is returned.
- Parameters:
interval
- the interval to examine, null means ISO in the default zone
- Returns:
- the chronology, never null
public static final PeriodType getPeriodType(PeriodType type)
Gets the period type handling null. If the zone isnull
,PeriodType.standard()
will be returned. Otherwise, the type specified is returned.
- Parameters:
type
- the time zone to use, null means the standard type
- Returns:
- the type to use, never null
public static final ReadableInterval getReadableInterval(ReadableInterval interval)
Gets the interval handling null. If the interval isnull
, an interval representing now to now in theISOChronology
will be returned. Otherwise, the interval specified is returned.
- Parameters:
interval
- the interval to use, null means now to now
- Returns:
- the interval, never null
- Since:
- 1.1
public static final DateTimeZone getZone(DateTimeZone zone)
Gets the zone handling null. If the zone isnull
,DateTimeZone.getDefault()
will be returned. Otherwise, the zone specified is returned.
- Parameters:
zone
- the time zone to use, null means the default zone
- Returns:
- the time zone, never null
public static final boolean isContiguous(ReadablePartial partial)
Checks whether the partial is contiguous. A partial is contiguous if one field starts where another ends. For exampleLocalDate
is contiguous because DayOfMonth has the same range (Month) as the unit of the next field (MonthOfYear), and MonthOfYear has the same range (Year) as the unit of the next field (Year). Similarly,LocalTime
is contiguous, as it consists of MillisOfSecond, SecondOfMinute, MinuteOfHour and HourOfDay (note how the names of each field 'join up'). However, a Year/HourOfDay partial is not contiguous because the range field Day is not equal to the next field Year. Similarly, a DayOfWeek/DayOfMonth partial is not contiguous because the range Month is not equal to the next field Day.
- Parameters:
partial
- the partial to check
- Returns:
- true if the partial is contiguous
- Since:
- 1.1
public static final void setCurrentMillisFixed(long fixedMillis) throws SecurityException
Sets the current time to return a fixed millisecond time. This method changes the behaviour ofcurrentTimeMillis()
. Whenever the current time is queried, the same millisecond time will be returned.
- Parameters:
fixedMillis
- the fixed millisecond time to use
public static final void setCurrentMillisOffset(long offsetMillis) throws SecurityException
Sets the current time to return the system time plus an offset. This method changes the behaviour ofcurrentTimeMillis()
. Whenever the current time is queried,System.currentTimeMillis()
is used and then offset by adding the millisecond value specified here.
- Parameters:
offsetMillis
- the fixed millisecond time to use
public static final void setCurrentMillisSystem() throws SecurityException
Resets the current time to return the system time. This method changes the behaviour ofcurrentTimeMillis()
. Whenever the current time is queried,System.currentTimeMillis()
is used.
