[MonoTouch] UIDatePicker - AM/PM : Getting it exactly the wrong way around.

2012-07-10 Thread Phil Cockfield 
I'm using a *UIDatePicker *control in a pretty standard way (I think).
 That is, I'm not setting much configuration at all at initialization:

Control = new UIDatePicker(RectangleF.Empty){ AutoresizingMask =
UIViewAutoresizing.FlexibleWidth };


The problem is, when I read the selected *Date* value out of it, the AM/PM
values are exactly the wrong way around.  Eg. 1PM is being returned as 1AM
and vice versa.

Here's a GIST of the entire code I've got (for context):

https://gist.github.com/3082372


Is this some kind of time-zone wierdness.  I'm in NZ.  Doesn't seem like
it's time-zones though, because it's an exact reversal of the AM/PM values,
not a shift in the time.

Thanks!

Hi,

I think the date picker handles date/time internally in some way, so I
use my date picker this way:

picker.Date = date.ToLocalTime();

date = DateTime.SpecifyKind(picker.Date, DateTimeKind.Local).ToLocalTime();

Does that help?

Mikkel

The dates that come out of pickers are GMT. You are GMT+12 :)

(I had the same problem developing TripWallet - I was in NZ then, too)

Thanks Nic - good to know it actually is a TimeZone issue.
 Being exactly 12 hours off made it look suspicious :)

There must be some other trick, beyond what Mikkel was showing with the *
ToLocalTime*() methods to have it convert correctly.

Mikkel suggested this:

picker.Date = date.ToLocalTime();
date = DateTime.SpecifyKind(picker.Date, DateTimeKind.Local).ToLocalTime();


Were there other time localization calls you were making for TripWallet?

better. Mine is MESSY
