<DD>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
<a href="http://www.w3.org/TR/xmlschema-2/#dateTime">[3.2.7 dateTime]</a> of

If the argument is not in either of these formats, date:date returns an empty string ('').

<a href="http://www.w3.org/TR/xmlschema-2/">[XML Schema Part 2: Datatypes]</a> and
<a href="http://www.iso.ch/markete/8601.pdf">[ISO 8601]</a> 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.

<DD>The date:add function returns the date/time resulting from adding a duration to a date/time.
The first argument must be right-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:gYearMonth (CCYY-MM)
xs:gYear (CCYY)
The second argument is a string in the format defined for xs:duration in [3.2.6 duration] of
[XML Schema Part 2: Datatypes].
The return value is a right-truncated date/time strings in one of the formats defined in
[XML Schema Part 2: Datatypes] and listed above.
This value is calculated using the algorithm described in
[Appendix E Adding durations to dateTimes] of [XML Schema Part 2: Datatypes].

<DD>The date:sum function adds a set of durations together.
The string values of the nodes in the node set passed as an argument
are interpreted as durations and added together as if using the date:add-duration
function. The string values of the nodes in the node set passed as the argument
must be in the format defined for xs:duration in [3.2.6 duration] of
[XML Schema Part 2: Datatypes]. If any of the string values of these nodes
are not in this format, or if the node set is empty, the function returns an
empty string (''). The result is a string in the format defined for xs:duration
in [3.2.6 duration] of [XML Schema Part 2: Datatypes].
The durations can be summed by summing the numbers given for each of the components in the durations.

Both arguments are strings in the format defined for xs:duration in [3.2.6 duration] of

an empty string (''). The return value is a string in the format defined for xs:duration in
[3.2.6 duration] of [XML Schema Part 2: Datatypes]. The durations can usually be added by
summing the numbers given for each of the components in the durations. However, if the durations
are differently signed, then this sometimes results in durations that are impossible to express
in this syntax (e.g. 'P1M' + '-P1D'). In these cases, the function returns an empty string ('').

<DL>
<DD>The date:difference function returns the duration between the first date and the second date.
If the first date occurs before the second date, then the result is a positive duration;
if it occurs after the second date, the result is a negative duration.
The two dates must both be right-truncated date/time strings in one of the formats defined in
[XML Schema Part 2: Datatypes].
The date/time with the most specific format (i.e. the least truncation) is converted into the
same format as the date with the most specific format (i.e. the most truncation).
The permitted formats are as follows, from most specific to least specific:
xs:dateTime (CCYY-MM-DDThh:mm:ss)
xs:date (CCYY-MM-DD)
xs:gYearMonth (CCYY-MM)
xs:gYear (CCYY)
<p/>
If either of the arguments is not in one of these formats, date:difference
returns the empty string ('').
The difference between the date/times is returned as a string in the format defined for
xs:duration in [3.2.6 duration] of [XML Schema Part 2: Datatypes].
If the date/time string with the least specific format is in either xs:gYearMonth or xs:gYear format,
then the number of days, hours, minutes and seconds in the duration string must be equal to zero.
(The format of the string will be PnYnM.)
The number of months specified in the duration must be less than 12.
Otherwise, the number of years and months in the duration string must be equal to zero.
(The format of the string will be PnDTnHnMnS.)
The number of seconds specified in the duration string must be less than 60;
the number of minutes must be less than 60; the number of hours must be less than 24.

<DD>The date:duration function returns a duration string representing the number of seconds
specified by the argument string. If no argument is given, then the result of calling
date:seconds without any arguments is used as a default argument. The duration is returned
as a string in the format defined for xs:duration in [3.2.6 duration] of

must be equal to zero. (The format of the string will be PnDTnHnMnS.)
The number of seconds specified in the duration string must be less than 60;
the number of minutes must be less than 60; the number of hours must be less than 24.

<DL>
<DD>The date:seconds function returns the number of seconds specified by the argument string.
If no argument is given, then the current local date/time, as returned by date:date-time
is used as a default argument.
The argument string may be in one of the following formats:
1. A right-truncated date/time string in one of the formats defined in
<a href="http://www.w3.org/TR/xmlschema-2/">[XML Schema Part 2: Datatypes]</a>.
In these cases, the difference between the date/time string and 1970-01-01T00:00:00Z
is calculated as with date:difference and the result is converted to seconds with
date:seconds.
The legal formats are as follows:
xs:dateTime (CCYY-MM-DDThh:mm:ss)
xs:date (CCYY-MM-DD)
xs:gYearMonth (CCYY-MM)
xs:gYear (CCYY)
2. A duration specified in days, hours, minutes and seconds in the format defined for
xs:duration in
<a href="http://www.w3.org/TR/xmlschema-2/#duration">[3.2.6 duration]</a>
of
<a href="http://www.w3.org/TR/xmlschema-2/">[XML Schema Part 2: Datatypes]</a>.
The number of years and months in the duration string must both be equal to zero:
either P0Y0M120D or P120D are permitted, but P3M is not.
If the argument to date:seconds is defined as a duration, the number returned is the
result of converting the duration to seconds by assuming that
1 day = 24 hours, 1 hour = 60 minutes and 1 minute = 60 seconds.
The permitted duration format is basically PnDTnHnMnS, although implementers should
consult
<a href="http://www.w3.org/TR/xmlschema-2/">[XML Schema Part 2: Datatypes]</a>
and
<a href="http://www.iso.ch/markete/8601.pdf">[ISO 8601]</a>
for details.
If the argument is not in any of these formats, date:seconds returns NaN.
