Display elapsed time in hours, minutes, and seconds

Since now datestr is discouraged, I would like to use datetime to display elapsed time in hours, minuts and seconds. My previous code was

datestr(toc, 'HH:MM:SS')

How can I replace this with a command using datetime?

Answer 1

[chicken vector]

time = seconds(4321)
time.Format = 'hh:mm:ss'

Thank you!

But is there also a one-liner? I have put my command within the composition of a message, and it would be nice to not break it into several pieces...

I tried

datetime(toc,'Format','HH:mm:ss')

or

datetime(seconds(toc),'Format','HH:mm:ss')

but both give errors.

I tried

datetime(toc,'Format','yyyy-MM-dd HH:mm:ss.SSS')

or

datetime(seconds(toc),'Format','yyyy-MM-dd HH:mm:ss.SSS')

but that gives an error.

time = duration(0,0,4321)

Oh Wow! That's perfect! Thank you!!

I just noticed that one can even print milliseconds using

time = duration(0,0,toc, 'Format', 'hh:mm:ss.SSSS')

the command seconds is returning an instance of the class duration, that's why you can include the 'Format' command in duration, but not in seconds.
