The Date class lets you retrieve date and time values relative to universal time (Greenwich
mean time, now called universal time or UTC) or relative to the operating system on which
Flash Player is running. The methods of the Date class are not static but apply only to the
individual Date object specified when the method is called. The
Date.UTC()
method is an
exception; it is a static method.
The Date class handles daylight saving time differently, depending on the operating system
and Flash Player version. Flash Player 6 and later versions handle daylight saving time on the
following operating systems in these ways:
■
Windows - the Date object automatically adjusts its output for daylight saving time. The
Date object detects whether daylight saving time is employed in the current locale, and if
so, it detects the standard-to-daylight saving time transition date and times. However, the
transition dates currently in effect are applied to dates in the past and the future, so the
daylight saving time bias might calculate incorrectly for dates in the past when the locale
had different transition dates.
■
Mac OS X - the Date object automatically adjusts its output for daylight saving time. The
time zone information database in Mac OS X is used to determine whether any date or
time in the present or past should have a daylight saving time bias applied.
■
Mac OS 9 - the operating system provides only enough information to determine whether
the current date and time should have a daylight saving time bias applied. Accordingly, the
date object assumes that the current daylight saving time bias applies to all dates and times
in the past or future.
Flash Player 5 handles daylight saving time on the following operating systems as follows:
■
Windows - the U.S. rules for daylight saving time are always applied, which leads to
incorrect transitions in Europe and other areas that employ daylight saving time but have
different transition times than the U.S. Flash correctly detects whether daylight saving
time is used in the current locale.
To call the methods of the Date class, you must first create a Date object using the constructor
for the Date class, described later in this section.
