Method Detail
-
dateTime
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 lexical representation of xs:dateTime in [3.2.7 dateTime] of [XML Schema Part 2: Datatypes]. 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/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.
-
date
public static java.lang.String date(java.lang.String datetimeIn) throws java.text.ParseException
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.- Throws:

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.

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:gYear (CCYY)
- xs:gMonthDay (--MM-DD)
- xs:gMonth (--MM--)
- xs:gDay (---DD)
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.
