Enum Constant Detail

OOXML_1900

public static final DateConverter.DateFormat OOXML_1900

1900 epoch with negative value support as used in OOXML.

Lower limit: -9999/01/01 00:00:00, value -4 346 018
Epoch date: 1899/12/30 00:00:00, value 0
Upper limit: 9999/12/31 23:59:59, value 2 958 465.999 988 4

LEGACY_1900

public static final DateConverter.DateFormat LEGACY_1900

1900 epoch without negative value support as used in BIFF8.

Epoch date: 1899/12/31 00:00:00, value 0
Lower limit: 1900/01/01 00:00:00, value 1
Upper limit: 9999/12/31 23:59:59, value 2 958 465.999 988 4

In this system 1900 is (incorrectly) considered a leap year. Serial dates after 1900/02/28 are one higher than they otherwise should be and the value 60 is unmapped.

LEGACY_1904

public static final DateConverter.DateFormat LEGACY_1904

1904 epoch without negative value support as used by Excel for Mac.

Epoch date: 1904/01/01 00:00:00, value 0
Lower limit: 1904/01/01 00:00:00, value 0
Upper limit: 9999/12/31 23:59:59, value 2 957 003.999 988 4

Method Detail

values

public static DateConverter.DateFormat[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DateConverter.DateFormat c : DateConverter.DateFormat.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DateConverter.DateFormat valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getEpochDelta

protected int getEpochDelta()

getLowerLimit
