c++ - When should specific constructors be implemented? -

If my class has different attributes, for example the following code:

  Class status {double latitude; Double longitude; Double height; Pausx Time Time; };  

So we say that this is the class that I want to make, where is the time (currently in the development of the current time) always current time < / Strong>. I do not currently use any other time, it is always the creation time, should I still apply a manufacturer with a time parameter? Maybe it's used later or by any other developer? In short, there are two options:

1. Writing only 2 constructs:

     position (): latitude (0), longitude (0), alitutde ( 0), Time (PosixCurrentTime ()) {} Status (double latitude, double loan, double alt): Latitude (latitude), longitude, alitutde (alt), time (PosixCurrentTime ()) {}  <3 Write the constructors (both above and below): 
    
     position (double latitude, double lawn, double alt, poketime t): latitude (latitude), longitude (loan), alitutde ( Alt), time (t) {}
