Iff the subject is a xsd:dateTime
and the object is the integer day component of the dateTime.
the object can be calculated as a function of the subject.
Iff the subject is a xsd:dateTime
and the object is the integer the day number within the week, Sunday being 0.
the object can be calculated as a function of the subject.
Iff the subject is a dateTime format string and the object is the
result of formatting the Universal Time of processing in the format given.
If the format string has zero length,
then the ISOdate standard format is used.
[ is time:gmtime of ""]
the therefore the current date time.
It will end with "Z" as a timezone code.
the object can be calculated as a function of the subject.
Rules which use this function will of course NOT be repeatable.
Iff the subject is a xsd:dateTime
and the object is the integer hours component of the dateTime.
the object can be calculated as a function of the subject.
Iff the subject is a xsd:dateTime
and the object is the integer number of seconds
since the beginning of the era on a given system. Don't assume a particular value, always test for it.
the object can be calculated as a function of the subject.
Cwm implements this as a bidirectional function: you can calculate the ISO date from the seconds since the beginning of the era, or vice-versa.
Iff the subject is a dateTime format string and the object is the
result of formatting the current time of processing and local timezone in the format given.
If the format string has zero length,
then the ISOdate standard format is used.
[ is time:gmtime of ""]
the therefore the current date time.
It will end with "Z" as a timezone code.
the object can be calculated as a function of the subject.
Rules which use this function will of course NOT be repeatable.
Iff the subject is a xsd:dateTime
and the object is the integer minutes component of the dateTime.
the object can be calculated as a function of the subject.
Iff the subject is a xsd:dateTime
and the object is the integer month component of the dateTime.
the object can be calculated as a function of the subject.
Iff the subject is a xsd:dateTime
and the object is the integer seconds component of the dateTime.
the object can be calculated as a function of the subject.
Iff the subject is a xsd:dateTime
and the object is the trailing timezone offset
part, e.g. "-05:00"..
the object can be calculated as a function of the subject.
Iff the subject is a xsd:dateTime
and the object is the integer year component of the dateTime.
the object can be calculated as a function of the subject.
