unlocalize template filter not consistent with "localize off" for datetimes - does not honor DATETIME_FORMAT

[Beda Kosata]

Hello,

according to the documentation, using {% localize off %}{{ variable }}{% endlocalize %} should be equivalent to {{ variable|unlocalize }}. However, for datetimes the former formats the variable according to DATETIME_FORMAT setting, while the latter does not and uses some default ISO based formatting.

To make a suggestion, I think that the source for the ulocalize filter should be:

@register.filter(is_safe=False)
def unlocalize(value):
    """
    Forces a value to be rendered as a non-localized value,
    regardless of the value of ``settings.USE_L10N``.
    """
    return force_text(formats.localize(value, use_l10n=False))

instead of

@register.filter(is_safe=False)
def unlocalize(value):
    """
    Forces a value to be rendered as a non-localized value,
    regardless of the value of ``settings.USE_L10N``.
    """
    return force_text(value)

Best regards
