how I do header extraction from file?

Hi all, I extracted the numeric data from .tuv file but I still need to extract the date and time which is in the form of

 %TimeStamp: 2017 07 02  05 00 00

the above line is just for one file, so I want to extract it from all files. how can I do that?

Thank you so much

S = '%TimeStamp: 2017 07 02  05 00 00';

datetime(sscanf(S, '%%TimeStamp: %d%d%d%d%d%d').')
