DateTime Class

A class to a represent a date/time as defined by the XML w3c

Base Classes:

Implemented interfaces:

Date and Time manipulation class provided as part of the Liquid XML Data Binding Runtime.

Supports the W3C XML Schema specification subset of the ISO 8601 standard.
The date uses the proleptic Gregorian calendar, this means that dates previous to the invent
of the Gregorian calendar are still held as Gregorian dates.

The Minimum Date represents -9999-12-31T23:59:59.999999999
The Maximum Date represents 9999-12-31T23:59:59.999999999

NOTE: DateTime uses the XML Schema formula for proleptic Gregorian calendar where year 0 is illegal and -4 (4BC) as a leap year.

The Type of value held in the DateTime will differ depending on the way the DateTime is constructed. The Type
value is immutable and is taken from the XML Schema subset of the ISO 8601 standard as follows:

dateTime (DTType_dateTime) comprises [-]CCYY-MM-DDThh:mm:ss[.ff][[Z]|[[+|-]hh:mm]]
date (DTType_date) comprises [-]CCYY-MM-DD[[Z]|[[+|-]hh:mm]]
gDay (DTType_gDay) comprises ---DD[[Z]|[[+|-]hh:mm]]
gMonth (DTType_gMonth) comprises --MM[[Z]|[[+|-]hh:mm]]
gYear (DTType_gYear) comprises [-]CCYY[[Z]|[[+|-]hh:mm]]
gMonthDay (DTType_gMonthDay) comprises --MM-DD[[Z]|[[+|-]hh:mm]]
gYearMonth (DTType_gYearMonth) comprises [-]CCYY-MM[[Z]|[[+|-]hh:mm]]
time (DTType_time) comprises hh:mm:ss[.ff][[Z]|[[+|-]hh:mm]]

The parts in [...] are optional, everything else is mandatory where:

'+', '-', ':', '.', 'T' and 'Z' = literal values
CCYY = Year (-9999 <= CCYY <= 9999 && CCYY != 0000)
MM = Month (01 <= MM <= 12)
DD = Day (01 <= DD <= DaysInMonth)
hh = Hour (00 <= hh <= 23)
mm = Minute (00 <= mm <= 59)
ss = Second (00 <= ss <= 59)
ff = Fraction of Second (0 <= ff <= 999999999)
