BaseDateTimeField
For example, a leap year would return true, a non leap year would return false.
This implementation returns false.

BaseDateTimeField
For example, a leap year would return one, a non leap year would return zero.
This implementation returns zero.

public long roundFloor(long instant)
BaseDateTimeField
For example, a datetime of 2002-11-02T23:34:56.789, rounded to the lowest whole hour is 2002-11-02T23:00:00.000.
roundFloor
in class DecoratedDateTimeField
instant
- the milliseconds from 1970-01-01T00:00:00Z to roundpublic long roundCeiling(long instant)
BaseDateTimeField
For example, a datetime of 2002-11-02T23:34:56.789, rounded to the highest whole hour is 2002-11-03T00:00:00.000.
The default implementation calls roundFloor, and if the instant is modified as a result, adds one field unit. Subclasses are encouraged to provide a more efficient implementation.

BaseDateTimeField
If the millisecond value is exactly halfway between the floor and ceiling, the ceiling is chosen over the floor only if it makes this field's value even.
roundHalfEven
in class BaseDateTimeField
instant
- the milliseconds from 1970-01-01T00:00:00Z to roundpublic long remainder(long instant)
BaseDateTimeField
For example, on a datetime of 2002-11-02T23:34:56.789, the remainder by hour is 34 minutes and 56.789 seconds.
The default implementation computes
instant - roundFloor(instant)
. Subclasses are encouraged to
provide a more efficient implementation.

instant
- the milliseconds from 1970-01-01T00:00:00Z to get the
