Time when item was last read


TimeStamp indicates the time when the Value and Quality properties were obtained by the device (if this is available) or the time the server updated or validated Value and Quality in its cache. TimeStamp is updated when you perform an asynchronous or synchronous read operation or when a subscription callback occurs.

TimeStamp is stored as a MATLAB® date vector. You convert date vectors to date character vectors with the datestr function, and to MATLAB date numbers with the datenum function.
