You will need to take into consideration at least three existing standards which include time models. These are ISO 10303 STEP for industrial data with particular reference to its Product Lifecycle support standard, ISO 15531 MANDATE ( Manufacturing Management Data) and IEC 62264 which corresponds broadly to ISA SP.95. You should also take care to align with ISO 8601 - date/time.
