RE: [flexcoders] Flex dates and time zones.
Its because the timezone is not stored in the date, so what would it send. It should just send the date or at least have an option to do so.

RE: [flexcoders] Flex dates and time zones.
The problem is that somehow.
If the server serving that date is in a different location to you, flash
player says, well I wont show that date I just got from the database, I'll
adjust it to your time. This is totally useless, so for example if Im
logging actions in an audit, the date in those logs could look different
from one user to another.

I have a date in a server in Australia: 22/12/2008 12:00:00 AM
I am using this label function for the grid to try and fix the time zone

Any ideas?

Re: [flexcoders] Flex dates and time zones.
Here's what it comes down to...
The Date class in flash doesn't natively allow you to have a timezone other
than your local timezone and UTC.
Take this example (my computer is in PST time):
var myDate:Date = new Date("Mon Dec 15 12:00:00 GMT-0400 2008");
trace(myDate.toString());
trace(myDate.toUTCString());
Output:
Mon Dec 15 08:00:00 GMT-0800 2008
Mon Dec 15 16:00:00 2008 UTC
So if someone passes a DateTime from a server that has a timezone offset
which differs from the local timezone of the client's machine. Flex doesn't
save that offset when it's unmarshalled. If you pass them as a string, the
timezone data is preserved.
HTH,
Nate

Re: [flexcoders] Flex dates and time zones.
If you're in the US, you're unlikely to run up against these issues at all.
The problem is, computers think about dates and times attached to timezones,
but most of the time our clients do not. That and Flash has no "date-only"
object, whereas people want to use dates instead of datetimes all over the
place.

RE: [flexcoders] Flex dates and time zones.
I guess I really don't understand what the problem is here?? I have a
smalldatetime (or a datetime) in a MSSQL database. I setup a value object in
AS to have the date field as a Date object. I go get the date from
ColdFusion using RemoteObject. The cfc sets up a CF "value object" with the
date as a CF Date object. And, voila, the MSSQL datetime becomes an AS Date
object.
I don't have to convert anything to a string, or any other kind of object.
So, what's the problem here???

Why does Flex do this?
If I get a date out of the db and want to deal with it as a date, surely
this should be possible. How can the flash player determine it needs to
change it to a different date.
There must be some other option rather than converting to a string.

Re: [flexcoders] Flex dates and time zones.
I've had a fair bit of experience wrestling date problems in Flex; Aside
from the fact that SchemaManager marshalls xsi:Date as Zulu time instead of
local (which isn't technically incorrect, just annoying as hell for us
aussies), every time there's a problem it's because Flex is doing the right
thing, and the server is sending an incorrect value, or what the clients
actually want is not possible without also passing along the server timezone
in another field.
For you aussies out there, the easiest way to cut down on these problems is
to use midday instead of midnight when you're referring to an "all day" date
using a Flash Date or xsi:DateTime. We do this by filtering requests and
responses on the server-side, and a subclass of DateField that sets the time
values to midday (as well as letting you 'unset' the date value) on the
client side.
If you're getting yesterday in Flex when you mean today, you've usually got
00:00:00+10:00 on the server, and it's getting truncated after being
converted to Zulu for transport somewhere. Or, you're setting a midnight
date in NSW which is +11 at the moment, and the client machine is in
Queensland which is still +10, or somewhere else which is further West. Your
server sends "(today)T00:00:00+11:00", which may or may not get converted to
Zulu as "(yesterday)13:00:00Z" in transport. The client correctly interprets
this as "23:00:00+10:00" on the client machine, which is then truncated when
displaying as date-only display field.
Basically, if you want clients in timezone X to show times that are in
timezone Y, you need to have timezone Y be part of the information you're
sending alongside the actual datetime value, or send strings.

Re: [flexcoders] Flex dates and time zones.
I'm working on timezone support within flash that I'm going to release as
open source very soon. I'll update this thread when I do.
But Tracy is right, you can always just pass a string from the server.
