realtimeinit
============

set time unit



realtime
========

set dates origin or waits until date



Calling Sequence
~~~~~~~~~~~~~~~~


::

    realtimeinit(time_unit)
    realtime(t)




Arguments
~~~~~~~~~

: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
