How to display datetime value or duration value in Edit Fields (Numeric or String)

I have two timestamps that I will like to display on my app created by App Designer. One is in datetime format and the other in duration. Now, I have tried using both the numeric edit field and the string edit field but I get the same error message.

Error using matlab.ui.control.EditField/set.Value (line 98)

'Value' must be a character vector or a string scalar.

Any ideas? Thanks!

Well, yes, do what the error says -- convert the datetime and/or duration to string representation.

>> dt=datetime(datestr(now));       % create a datetime variable
>> datestr(dt)
dt =
    '28-Jun-2022 09:27:41'
>> 

The format is/can be set by the 'Format' property of the datetime variable as desired.

>> du=timeofday(datetime(datestr(now)));  % for duration
>> string(du)
du = 
    "09:30:52"
>> char(du)
du =
    '09:32:08'
>> cellstr(du)
du =
  1×1 cell array
    {'09:32:19'}
>> datestr(du)
ans =
    ' 9:30 AM'
>> timeofday(datetime(datestr(now)))    
>>

your choice -- NB: datestr on the duration doesn't preserve the leading zero with the default formatting.
