I needed a UTC Timestamp as a default value and so modified Daniel's solution like this:

    [Column(TypeName = "datetime2")]
    [XmlAttribute]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
    [Display(Name = "Date Modified")]
    [DateRange(Min = "1900-01-01", Max = "2999-12-31")]
    public DateTime DateModified {
        get { return dateModified; }
        set { dateModified = value; } 
    }
    private DateTime dateModified = DateTime.Now.ToUniversalTime();
