Interface XMPDateTime

All Superinterfaces:

java.lang.Comparable<java.lang.Object>

All Known Implementing Classes:

XMPDateTimeImpl

public interface XMPDateTime
extends java.lang.Comparable<java.lang.Object>

The XMPDateTime-class represents a point in time up to a resolution of nano seconds. Dates and time in the serialized XMP are ISO 8601 strings. There are utility functions to convert to the ISO format, a Calendar or get the Timezone. The fields of XMPDateTime are:

• month - The month in the range 1..12.
• day - The day of the month in the range 1..31.
• minute - The minute in the range 0..59.
• hour - The time zone hour in the range 0..23.
• minute - The time zone minute in the range 0..59.
• nanoSecond - The nano seconds within a second. Note: if the XMPDateTime is converted into a calendar, the resolution is reduced to milli seconds.
• timeZone - a TimeZone-object.

DateTime values are occasionally used in cases with only a date or only a time component. A date without a time has zeros for all the time fields. A time without a date has zeros for all date fields (year, month, and day).

tz - a time zone to set

hasDate

boolean hasDate()

This flag is set either by parsing or by setting year, month or day.

Returns:

Returns true if the XMPDateTime object has a date portion.

hasTime

boolean hasTime()

This flag is set either by parsing or by setting hours, minutes, seconds or milliseconds.

Returns:

Returns true if the XMPDateTime object has a time portion.
