How to call srand() with time()?

```
void main()
{
     import core.stdc.stdlib : rand, srand;
     import core.stdc.time : time;
     srand(time(null));
}
```

Error: function core.stdc.stdlib.srand(uint seed) is not callable 
using argument types (long)
cannot pass argument time(null) of type long to parameter uint 
seed

And how to use the d libs instead? is this the way to go?

```
Random rnd = Random(Clock.currTime().second);
uniform01(rnd); //(or whatever)
```

Its already initialized on module load.

If you do want to custom seed it, you'll probably want to cast the seed 
to uint instead and have your own instance of the random number generator.
