Localized date/time placeholders produce unexpected results.

Example code:

```
*nLabel Clock

Clock
{
  AlwaysOnTop True
  X 50
  Y 50
  Width 150
  Height 30

  Font
  {
    Size 14
    Color #c1c1c1
  }

  Text
  {
    - "[Time('%c')]"
    Align center
    VerticalAlign Middle
  }
}
```

The output is "mm/dd/yy HH:mm:ss" regardless of locale.
Just for tests, I set time to "hh:mm:ss tt" but the label still show 24-h format.
