Nothing was useful for me guys....

So I added 1 extra field to the Model and will keep DateTime like a String in the format I need.

And for places I need DateTime format I have another field.

[Display(Name = "Expected Ending Time")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime? ExpectedEndingTime { get; set; }


[Required]
[Display(Name = "Expected Ending Time")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public string ExpectedEndingTimeAsString { get; set; }
