    create_time: Option<SystemTime>,
    update_time: Option<SystemTime>,
}
```
### Usage
```rust
pub fn test() {
    let meta = Test::meta();
    println!("{:?}", meta);
    // ("test", [("id", "bigserial primary key", 0, "", true), ("title", "varchar", 0, "", false), ("create_time", "timestamp", 0, "", false), ("update_time", "timestamp", 0, "", false)])
