I've also ran accross this, not so much a bug though. It works properly in
its use case. The problem is, there are other use cases with timezones.
Here is my scenario:
I work with a legacy database. Unfortunately, all datetimes are saved into
the database as UTC, but as the clients time zone.
So say someone in the EST -5 UTC and someone at PST -8 UTC both saved at the
same moment in time (5am EST). The database would have saved the dates as
following:
EST - 05:00
PST - 02:00
I can't change the behavior due to only being one piece in the grand scheme
of the application. The problem is, the databse doesnt' know what timezone
these are. The system was designed to just show that datetime to the user
if they ask for it. Flash/Flex always converts AMF Dates to the local
timezone. I've asked for a way to hook into that deserialization, but I
haven't gotten a response.
Therefore, I massage every date I receive and every date I send using the
following...
*
public* *static* *function* getUTCDate(myDate:Date):Date
{
*if* (myDate == *null*)
*return* *null*;
*else
*
*return* *new* Date(myDate.fullYearUTC, myDate.monthUTC, myDate.dateUTC,
myDate.hoursUTC, myDate.minutesUTC, myDate.secondsUTC,
myDate.millisecondsUTC);
}
*public* *static* *function* sendUTCDate(myDate:Date):Date
{
*if* (myDate == *null*)
*return* *null*;
*else
*
{
*var* sDate:Date = *new* Date(Date.UTC(myDate.fullYear, myDate.month,
myDate.date, myDate.hours, myDate.minutes, myDate.seconds,
myDate.milliseconds));
*return* sDate;
}
}
Hope this helps, but I hope even more there is a better solution out
there!!!!

nope. I can't find any mention of this anywhere. Might be known to
some flash pros, but a flash pro I am not. I suppose this is only a issue
if you want times always displayed based on a fixed timezone regardless of
where the user is. I have not confirmed this behavior using coldfusion on
the back end, just Java.
In our case, we are able to code around this by using rationals instead of
date fields, a soon to be used fix. We just need a start time and end time
between 6am to 10pm and have a separate field with only the date. so we can
refactor to use some rational between 6 and 22.
