Hello Pascal, it seems you double pasted the format in 2nd argument position instead indicating inputformat option :

> → duration(“00:00:26.310”,“InputFormat”, “hh:mm:ss.SSS”)
> 
> ans = [duration]
> 
> 00:00:26.310

yes i did, but there was another error whilst i had blanks but still. should there be a problem, if both input and output are the same, should it not be recognised as it is?

Hello @pascal

Can you send an example to reproduce the problem?

Best regards.

its more a philosophical question, should it not know that there is an input and an output format, and if both are the same, it should not care?  
duration(“00:00:26.310”,“hh:mm:ss.SSS”,“hh:mm:ss.SSS”)

There is no philosophical question here, this is a misuse of `duration`, as the valid syntaxes are well defined (see [duration - Create a duration - duration in hours, minutes and seconds](https://help.scilab.org/docs/2026.0.0/en_US/duration.html))

```auto
d = duration(h, m, s)
d = duration(h, m, s, ms)
d = duration(x)
d = duration(str)
d = duration(str, "InputFormat", inputFormat)
d = duration(..., "OutputFormat", outputFormat)

```

Ah, yes, now I see, it’s the placement of command and format twice of input and output.

Thanks, Pascal
