DateTime / DateTime Deserialize without timezone

[nicram-cf]

Hello,
I try to achieve 'Y-m-d' (without time, that string I get from external soap source) date format from serialize and deserialize.

    /**
     * @ORM\Column(type="date_immutable")
     * @JMS\Type("DateTimeImmutable<'Y-m-d','','Y-m-d'>")
     *
     */
    private $startDate;

This generates error:

Unexpected token "'" (_apostrophe) at line 1 and column 28:
DateTimeImmutable<'Y-m-d','','Y-m-d'>

With DateTime is the same.
