Datetime won't recognise some cells
Mostra commenti meno recenti
I have a series of datetimes in the format 'HH:mm:ss.sss'. I am using the following code to convert from string into datetimes.
data.TimeofDay = datetime(data.TimeofDay,'Format','HH:mm:ss.sss')
In the attached .mat file, it contains the data file before and after the command above. For some reason, different values in the column are returned as NaT despite all rows seemingly being in the same format.

Relevant for both your code and some of the answers:
- 'Format' governs what the output looks like
- 'InputFormat' governs what the input looks like
In your case, I believe MATLAB would have correctly inferred your input format, if had you left it unspecified:
datetime(data.TimeofDay)
Risposta accettata
For miliseconds, you want to use a capital 'S'.
load datetime-problem.mat
datetime(databackup.TimeofDay,'Format','HH:mm:ss.sss')
% corrected
datetime(databackup.TimeofDay,'Format','HH:mm:ss.SSS')

Two minor but important changes to your syntax:
datetime(data.TimeofDay,'InputFormat','HH:mm:ss.SSS')
Note that I used
- 'InputFormat' instead of 'Format'
- .SSS instead of .sss
load datetime-problem.mat
databackup.TimeofDay
% original Format specification:
datetime(databackup.TimeofDay,'Format','HH:mm:ss.sss')
% corrected Format specification:
datetime(databackup.TimeofDay,'Format','hh:mm:ss.SSS')
