I have a model 'media.playlist':

class media_playlist(models.Model):

      _name = 'media.playlist'

      start = fields.Datetime('Start', required=True, help="Start Time", store=True)

      stop = fields.Datetime('Stop', required=True, compute='get_stop', store=True, readonly=False, help="End Time")

      @api.depends('start')

      def get_stop(self):

          from datetime import datetime, timedelta

          for p in self:

              if p.start:

                  p_start_date_obj = datetime.strptime(p.start, "%Y-%m-%d %H:%M:%S")

                  p.stop = p_start_date_obj + timedelta(hours=4)

I have a tree and a form view for this model and it all works ok and on record creation both fields get stored into a database using UTC timezone (which is the expected Odoo behavior).

Now, from my own javascript web view I somehow get the wrong values when I do the RPC call:

RPC.query({

    model: 'media.playlist',

    method: 'search_read',

    args: [[['id','=',1],], ['id','start','stop']],

}).then(function (results) { 

    var playlist_view = new Playlist(self, {'playlist': result[0]});

    playlist_view.appendTo(self.$el.find('#media_panel'));

});

A simple template to display the "Playlist" view:

<t t-name="Playlists">

     <div>

        <h4>Playlist</h4>

        <t t-esc="widget.playlist['start']">

        <t t-esc="widget.playlist['stop']">

     </div>

</t>

So my problem is that these two fields (start & stop) get displayed in UTC (the same tz as stored in db). So what am I doing wrong? It works ok on Odoo tree and form views I created using xml, but not on my custom javascript views.
