How to change programmaticaly the preferences item corresponding to the locale of datetime format

I try this command, there is no error but it doesn't work :

com.mathworks.services.Prefs.setStringPref('Locale','fr_FR');

I am looking for the preference name equivalent to : Preferences -> Command Window -> Datetime format -> Locale

I don't found it in matlab.prf

Hi @Laurent Fritz,

Preferences related to the Command Window, including the datetime format, are typically not directly accessible or modifiable through the matlab.prf file. However, you can programmatically set the datetime format for your session using MATLAB commands.

To set the datetime format to a specific locale programmatically, you can use the datetime.setDefaultFormats function:

datetime.setDefaultFormats('default','yyyy-MM-dd hh:mm:ss')

To learn more about the datetime function in MATLAB, please refer to the following documentation link:

https://www.mathworks.com/help/matlab/matlab_prog/set-display-format-of-date-and-time-arrays.html#:~:text=only%20their%20display.-,Default%20datetime%20Format,-You%20can%20set

Hope this works for you!

Thanks for your answer.

With datetime.setDefaultFormats unfortunately it can't set the locale language.

Changing via Preferences -> Command Window -> Datetime format -> Locale works correctly on MATLAB Online but it does not exist on MATLAB Mobile.

So I try to use com.mathworks.services.Prefs.setStringPref without success.
