Unity&c# Time Related

1.Unity Time Class

1/ Time.time said that from the game development to the present time, will be suspended with the game to stop the calculation.

2/ Time.timesincelevelload indicates that the time from the current scene start to date will also stop with the pause operation.

3/ Time.deltatime represents the current frame time from the previous frame, in seconds.

Timer through this use, update to add Time.deltatime, is the elapsed time

4/ Time.fixedtime represents the time at which the game starts in seconds, and the fixed time is updated at regular intervals (equivalent to fixeddeltatime) until the timing property is reached.

5/ Time.fixeddeltatime indicates that the Edit->projectsettings->time fixed timestep can be set automatically at the interval of a second, with updates at the physical and other fixing frame rates.

6/ Time.smoothdeltatime represents a smooth deltatime, according to the former
The value of the time weighted average of n frames.

7/ Time.timescale time scaling, the default value is 1, if set <1, indicating time slows down, if set >1, indicating time to speed up, can be used to speed up and deceleration game, very useful.

8/ Total frame number of Time.framecount

9/ Time.realtimesincestartup that the total time since the start of the game, even if the pause will continue to increase.

The 10/ time.captureframerate indicates that the frame rate per second is set, and then the real time is not considered.

11/ Time.unscaleddeltatime does not consider the timescale time and deltatime the same, if the timescale is set, it is invalid.

12/ Time.unscaledtime does not consider the timescale time is the same, if the timescale is set, it is invalid.

3. Time Stamp

A timestamp (timestamp), usually a sequence of characters, that uniquely identifies a moment of time.
Time stamp refers to the GMT January 01, 1970 00:00 00 seconds (Beijing time January 01, 1970 08:00 00 seconds) up to now the total number of milliseconds.

1/c# generates a timestamp: (here in seconds)

private static string Gettimestamp ()
{
    TimeSpan ts = datetime.utcnow-new DateTime (1970, 1, 1, 0, 0, 0, 0);  
    Return Convert.toint64 (TS. totalseconds). ToString ();  
}

2/c# timestamp converted to format time: (here in seconds)

Private datetime GetTime (string timeStamp)  
{  
  DateTime Dtstart = TimeZone.CurrentTimeZone.ToLocalTime (new DateTime (1970, 1, 1));  The timestamp start point reverts to the current time zone
  long ltime = long. Parse (TimeStamp + "0000000");//Convert to Long type  
  TimeSpan tonow = new TimeSpan (ltime);//time interval return
  Dtstart.add ( Tonow); Plus time interval to get target time
}
