如何在模型中设置格式DateTimeOffset？

public class MyModel
{
    [DataType(DataType.DateTimeOffset)]
    public DateTimeOffset MyDateTimeOffset { get; set; }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<MyModel>()
        .Property(m => m.MyDateTimeOffset)
        .HasColumnType("datetimeoffset");
}

public class MyModel
{
    [DataType(DataType.DateTimeOffset)]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd HH:mm:ss zzz}")]
    public DateTimeOffset MyDateTimeOffset { get; set; }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<MyModel>()
        .Property(m => m.MyDateTimeOffset)
        .HasColumnType("datetimeoffset")
        .HasAnnotation("DisplayFormat", "{0:yyyy-MM-dd HH:mm:ss zzz}");
}
