Some applications require high resolution timestamps. The PicoSeconds fields allow applications to specify timestamps with a resolution of 10 picoseconds. The actual size of the PicoSeconds field depends on the resolution of the UtcTime DataType. For example, if the UtcTime DataType has a resolution of 100 nanoseconds then the PicoSeconds field would have to store values up to 10 000 in order to provide the resolution of 10 picoseconds. The resolution of the UtcTime DataType depends on the Mappings defined in OPC 10000-6.
