Some applications require high resolution timestamps. The PicoSecondsfields allow applications to specify timestamps with a resolution of 10 picoseconds. The actual size of the PicoSecondsfield depends on the resolution of the UtcTime DataType. For example, if the UtcTime DataTypehas a resolution of 100 nanoseconds then the PicoSecondsfield would need to store values up to 10 000 in order to provide the resolution of 10 picoseconds. The resolution of the UtcTime DataTypedepends on the Mappingsdefined in OPC 10000-6.
