Class IslamicDate

Extends IDate.
Construct a new civil Islamic date object. The constructor can be called with a params object that can contain the following properties:

julianday - the Julian Day to set into this date
year - any integer except 0. Years go from -1 (BCE) to 1 (CE), skipping the zero year
month - 1 to 12, where 1 means Muharram, 2 means Saffar, etc.
day - 1 to 30
hour - 0 to 23. A formatter is used to display 12 hour clocks, but this representation is always done with an unambiguous 24 hour representation
minute - 0 to 59
second - 0 to 59
millisecond - 0 to 999
locale - the TimeZone instance or time zone name as a string of this julian date. The date/time is kept in the local time. The time zone is used later if this date is formatted according to a different time zone and the difference has to be calculated, or when the date format has a time zone component in it.
timezone - the time zone of this instance. If the time zone is not given, it can be inferred from this locale. For locales that span multiple time zones, the one with the largest population is chosen as the one that represents the locale.
date - use the given intrinsic Javascript date to initialize this one.

If called with another Islamic date argument, the date components of the given date are copied into the current one.

If the constructor is called with no arguments at all or if none of the properties listed above from julianday through millisecond are present, then the date components are filled in with the current date at the time of instantiation. Note that if you do not give the time zone when defaulting to the current time and the time zone for all of ilib was not set with ilib.setTimeZone(), then the time zone will default to UTC ("Universal Time, Coordinated" or "Greenwich Mean Time").

Defined in: IslamicDate.js.
