| Methods Summary |
|---|
| public static java.lang.String | date(java.lang.String datetimeIn)The date:date function returns the date specified in the date/time string given
as the argument. If no argument is given, then the current local date/time, as
returned by date:date-time is used as a default argument.
The date/time string that's returned must be a string in the format defined as the
lexical representation of xs:dateTime in
[3.2.7 dateTime] of
[XML Schema Part 2: Datatypes].
If the argument is not in either of these formats, date:date returns an empty string ('').
The date/time format is basically CCYY-MM-DDThh:mm:ss, although implementers should consult
[XML Schema Part 2: Datatypes] and
[ISO 8601] for details.
The date is returned as a string with a lexical representation as defined for xs:date in
[3.2.9 date] of [XML Schema Part 2: Datatypes]. The date format is basically CCYY-MM-DD,
although implementers should consult [XML Schema Part 2: Datatypes] and [ISO 8601] for details.
If no argument is given or the argument date/time specifies a time zone, then the date string
format must include a time zone, either a Z to indicate Coordinated Universal Time or a + or -
followed by the difference between the difference from UTC represented as hh:mm. If an argument
is specified and it does not specify a time zone, then the date string format must not include
a time zone.

|
| public static java.lang.String | dateTime()The date:date-time function returns the current date and time as a date/time string.
The date/time string that's returned must be a string in the format defined as the

[ISO 8601] for details.
The date/time string format must include a time zone, either a Z to indicate Coordinated
Universal Time or a + or - followed by the difference between the difference from UTC
represented as hh:mm.

// Must also include offset from UTF.
// Get the offset (in milliseconds).
int offset = cal.get(Calendar.ZONE_OFFSET) + cal.get(Calendar.DST_OFFSET);
// If there is no offset, we have "Coordinated
// Universal Time."
if (offset == 0)

else
{
// Convert milliseconds to hours and minutes
int hrs = offset/(60*60*1000);
// In a few cases, the time zone may be +/-hh:30.
int min = offset%(60*60*1000);

|
| public static java.lang.String | dayAbbreviation(java.lang.String datetimeIn)The date:day-abbreviation function returns the abbreviation of the day
of the week of a date. If no argument is given, then the current local

|
| public static java.lang.String | formatDate(java.lang.String dateTime, java.lang.String pattern)The date:format-date function formats a date/time according to a pattern.
The first argument to date:format-date specifies the date/time to be
formatted. It must be right or left-truncated date/time strings in one of
the formats defined in
[XML Schema Part 2: Datatypes].
The permitted formats are as follows:
- xs:dateTime (CCYY-MM-DDThh:mm:ss)
- xs:date (CCYY-MM-DD)
- xs:time (hh:mm:ss)
- xs:gYearMonth (CCYY-MM)
- xs:gYear (CCYY)
- xs:gMonthDay (--MM-DD)
- xs:gMonth (--MM--)
- xs:gDay (---DD)
The second argument is a string that gives the format pattern used to
format the date. The format pattern must be in the syntax specified by
the JDK 1.1 SimpleDateFormat class. The format pattern string is
interpreted as described for the JDK 1.1 SimpleDateFormat class.
If the date/time format is right-truncated (i.e. in a format other than
xs:time, or xs:dateTime) then any missing components are assumed to be as
follows: if no month is specified, it is given a month of 01; if no day
is specified, it is given a day of 01; if no time is specified, it is
given a time of 00:00:00.
If the date/time format is left-truncated (i.e. xs:time, xs:gMonthDay,
xs:gMonth or xs:gDay) and the format pattern has a token that uses a
component that is missing from the date/time format used, then that token
is replaced with an empty string ('') within the result.

| public static java.lang.String | time(java.lang.String timeIn)The date:time function returns the time specified in the date/time string given
as the argument. If no argument is given, then the current local date/time, as
returned by date:date-time is used as a default argument.
The date/time string that's returned must be a string in the format defined as the
lexical representation of xs:dateTime in
[3.2.7 dateTime] of
[XML Schema Part 2: Datatypes].
If the argument string is not in this format, date:time returns an empty string ('').
The date/time format is basically CCYY-MM-DDThh:mm:ss, although implementers should consult
[XML Schema Part 2: Datatypes] and
[ISO 8601] for details.
The date is returned as a string with a lexical representation as defined for xs:time in
[3.2.8 time] of [XML Schema Part 2: Datatypes].
The time format is basically hh:mm:ss, although implementers should consult [XML Schema Part 2:
Datatypes] and [ISO 8601] for details.
If no argument is given or the argument date/time specifies a time zone, then the time string
format must include a time zone, either a Z to indicate Coordinated Universal Time or a + or -
followed by the difference between the difference from UTC represented as hh:mm. If an argument
is specified and it does not specify a time zone, then the time string format must not include
a time zone.

| public static double | weekInYear(java.lang.String datetimeIn)The date:week-in-year function returns the week of the year as a number. If no argument
is given, then the current local date/time, as returned by date:date-time is used as the
default argument. For the purposes of numbering, counting follows ISO 8601: week 1 in a year
is the week containing the first Thursday of the year, with new weeks beginning on a Monday.
The date/time string specified as the argument is a right-truncated string in the format
defined as the lexical representation of xs:dateTime in one of the formats defined in
[XML Schema Part 2: Datatypes]. The
permitted formats are as follows:
xs:dateTime (CCYY-MM-DDThh:mm:ss)
xs:date (CCYY-MM-DD)
If the date/time string is not in one of these formats, then NaN is returned.
String[] edz = getEraDatetimeZone(datetimeIn);

| public static double | year(java.lang.String datetimeIn)The date:year function returns the year of a date as a number. If no
argument is given, then the current local date/time, as returned by
date:date-time is used as a default argument.
The date/time string specified as the first argument must be a right-truncated
string in the format defined as the lexical representation of xs:dateTime in one
of the formats defined in
[XML Schema Part 2: Datatypes].
The permitted formats are as follows:
xs:dateTime (CCYY-MM-DDThh:mm:ss)
xs:date (CCYY-MM-DD)
xs:gYearMonth (CCYY-MM)
xs:gYear (CCYY)
If the date/time string is not in one of these formats, then NaN is returned.
