Hi,
I have a timer object, tmr:
%%my_timer_test
tmr = timer ...
( 'Name' , 'my_timer' ...
, 'TimerFcn' , @(~,~) my_script ...
, 'BusyMode' , 'drop' ...
, 'ExecutionMode' , 'fixedDelay' ...
, 'Period' , 600 ...
, 'StartDelay' , 1 ...
);
and a script, my_script.m:
%%my_script
disp(datestr(now,31))
How can I modfify the timer, so that it starts at 0900, fires every 10 minutes (600 seconds), and stops firing at 1200?
Any help would be appreciated!

I will be starting Matlab with a crontab each day around 0800, and want the time object start at 0900, fire at 10 minute intervals, with the final firing at 1200.

You need to set the delay depending on the time that the timer object is created. The number of calls can be either calculated or set.
x = datetime("now");
StartDelay = seconds( datetime([year(x) month(x) day(x) 19 0 0])-x );
% You can also hard-code this to 19 if you prefer.
NumberOfCalls = numel(datetime([0 0 0,9 0 0]):duration(0,10,0):datetime([0 0 0,12 0 0]));
tmr = timer ...
( 'Name' , 'my_timer' ...
, 'TimerFcn' , @(~,~) my_script ...
, 'BusyMode' , 'drop' ...
, 'ExecutionMode' , 'fixedDelay' ...
, 'Period' , 600 ...
, 'TasksToExecute', NumberOfCalls ...
, 'StartDelay' , StartDelay ...
);

This function: startat(t,firingTime), allows you specify the specific time to execute the timer, and is precsely what I'm looking for!
Appreciate your help!
