[1] International (IU) and United States Pharmacopeia (USP) units are defined in terms of comparison to a physical reference preparation; the mass or volume that constitutes one ‘unit’ varies based on which substance is being measured and the variance is based on the biological activity or effect. IU and USP units are used to quantify vitamins, hormones, some medications, vaccines, blood products, and other biologically active substances. Although the meaning of IU and USP units differs from substance to substance, comparisons to the underlying WHO or USP reference preparation can be made, facilitating interoperability across multiple institutions. In contrast, arbitrary units [arb’U] contain an arbitrary scale factor and preclude any meaningful comparison across multiple institutions (although comparability within a given institution may be possible).

MDC_ATTR_TIME_RES_REL_HI_RES . Specifies the resolution of the high resolution relative clock (if not the default value of 1 μs). For example, a clock that ticks at 1 s intervals would have a value of 1000000. 1::2688 IHE/Continua 1 68224
MDC_ATTR_TIME_RES_ABS . Specifies the resolution of the absolute date-time clock (if not the default value of 1/100 s). For example, a clock that ticks at 1 s intervals would have a value of 100. 1::2686 IHE/Continua 1 68222
MDC_ATTR_TIME_NTP_REF_ID . Specifies the four octet NTP “Reference Identifier” that identifies the clock reference source. This compact binary representation is dependent on the NTP version and NTP stratum of the clock reference source (IETF RFC 5905). 1::2698 10101a 1 68234
MDC_ATTR_TIME_TIMEBASE_ID . Specifes, as a text string, the universally unique identifier of the timebase providing the clock reference source. 1::2699 10101a 1 68235
