[6.1]Calculating datetime from date cause timezone issues in sales order

[Don Kirkby]

This may be similar to the hr_timesheet_sheet bug 943091, and is certainly related to the change in 6.1 to use UTC on all datetime fields in the server, as described in bug 925361. It sounds like the context_today() method helps when calculating date fields based on the current date, but how can we calculate a datetime based on a pure date?

The example scenario I have run into is confirming a sales order.

1. My OpenERP user timezone is -7:00 PDT. (Set in the OpenERP user preferences.)
2. I create a sales order with date 2012-05-01.
3. I confirm the sales order, and look at the picking list.

Expected behaviour: the picking list should have order date 2012-05-01 00:00:00. Also acceptable would be to ignore the sales order's order date, and use the current datetime for the picking list's order date as it did in version 5.0.
Actual behaviour: the picking list has order date 2012-04-30 17:00:00. This is 2012-05-01 midnight UTC adjusted for the user's time zone.

A similar problem exists on the procurement table when moving from the wizard's date field to the table's datetime field.

I am running 6.1.1 on Ubuntu 10.04.

Hello Don,

I have checked your issue .But, for me ,it's working fine.
For your more reference , I have attached video .Please take a look.

Waiting for your feedback..!!

Thanks!!

Thanks for trying to reproduce it, Ravish.

Please check that your OpenERP user time zone is set to PDT. In the video, it looked like you were checking your operating system's time zone setting. In the OpenERP menu, choose User: Preferences, and set the Timezone field to America/Vancouver.

What version of OpenERP are you testing? I just tested it at the 6.1.1 tag in the 6.1 branch, and it still has the problem for me.

I just came across another scenario of the same problem in the procurement screen. If I make a procurement for a product, and set the date in the wizard to 2012-11-01, then the scheduled date on the procurement will be 2012-10-31 17:00:00.
