public ExsltDatetime()

Method Detail

dateTime

public static XString 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 XString 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.

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.
