Scilab Function

realtimeinit - set time unit

realtime - set dates origin or waits until date

### Calling Sequence

  `realtimeinit(time_unit)`
  `realtime(t)`

### Parameters

- `time_unit` : a real number. The number of seconds associated to the `realtime` argument
- `t` : a real number. A date

### Description

These two functions can be used to handle real time into Scilab.

`realtimeinit(time_unit)` defines the time unit associated to the `realtime` argument `t`

first call to `realtime(t0)` sets current date to (`t0` ). subsequent calls to `realtime(t)` wait till date `t` is reached.

### Examples

       realtimeinit(1/2);//sets time unit to half a second
       realtime(0);//sets current date to 0
       for k=1:10,realtime(k);mprintf('current time is '+string(k/2)+'sec .\r\n');end

      //next instruction outputs a dot each 2 seconds
       realtimeinit(2); realtime(0);for k=1:10,realtime(k);mprintf('.\r\n');end

       realtimeinit(1);realtime(0);
       dt=getdate('s'); realtime(10);   getdate('s')-dt
