获取时间戳

方案一：

using UnityEngine;
 
public class TimeTest : MonoBehaviour

    private void Start()
    {

        //获取当前时间戳
        long unixTime = ConvertDateTimep(DateTime.Now);
        Debug.Log(unixTime);
        //将时间戳转换为DateTime
        Debug.Log(GetTime(unixTime.ToString()).ToString());
 
        Debug.Log(GetTime(unixTime.ToString()).Year);
        Debug.Log(GetTime(unixTime.ToString()).Month);
        Debug.Log(GetTime(unixTime.ToString()).Day);
        Debug.Log(GetTime(unixTime.ToString()).Hour);
        Debug.Log(GetTime(unixTime.ToString()).Minute);
        Debug.Log(GetTime(unixTime.ToString()).Second);
