Starting a Timer at a Specified Time

To start a timer object and specify when you want the timer to fire as a date and time, rather than as the number of seconds to elapse, use the startat function.

The startat function starts a timer object running and lets you specify the date, hour, minute, and second when you want to the timer to execute. You specify the time as a MATLAB serial date number or as a specially formatted date text string. See the startat function reference page for details.

This example creates a timer object that displays a message after an hour has elapsed. The startat function starts the timer object running and calculates the value of the StartDelay property based on the time you specify.

• t2=timer('TimerFcn','disp(''It has been an hour now.'')');
  
  startat(t2,now+1/24);
