Subject RE: Date without Time (Was: Re: Adobe Bugbase: Bug 3643917 Updated: Date/time gets messed up by the client locale time zone setting)
Date Tue, 08 Oct 2013 23:02:50 GMT
Hi,
Besides of the "Date without time" issue, there is also the issue handling regular Date+Time
in different TZ.
The requirement is to be able to do Math on Date+Time locally (not on the java side) that
is TZ aware, and manage DST properly.
I spent several months working on it and from what I understand, others did the same.
- What were the business requirements ?
- What techniques did people use to met the requirements ?
- Could we imagine having a decent implementation of this in pure Flex,  something like a
partial porting of eg. JodaTime to Flex ?
-  Is it "feasible" to change all the time-aware Flex components ( DateField, DateChooser,
Charts, etc.) so that they can use Date or something else (maybe through an interface as suggested
in this thread) ?

Maybe I should open another thread on that, not to pollute this one.

Regards,

Maurice

What about them?  For Doug and Mike, was it really easier to do custom AMF and timezone math
vs just creating a custom DateWithoutTime class and transfer the Date portion to/from the
Date values in the components?

What about current SDK methods and componente that require Date objects?
