|
|
Description: Date.prototype.getYear
|
|
|
|
This function is specified here for backwards compatibility only. The
|
|
function getFullYear is much to be preferred for nearly all purposes,
|
|
because it avoids the "year 2000 problem."
|
|
|
|
1. Let t be this time value.
|
|
2. If t is NaN, return NaN.
|
|
3. Return YearFromTime(LocalTime(t)) 1900.
