本标准定义:1）时间点SMPTE历元，用于校准本标准中引用的所有实时信号；2） 这些信号与SMPTE时代的一致性；3） 公式规定了自SMPTE纪元以来这些信号与时间的持续对齐；4） 公式规定了从SMPTE配置文件IEEE 1588-2008 PTP数据计算SMPTE ST 12-1时间地址值和SMPTE ST 309日期值。注:建议实施者成对阅读SMPTE ST 2059-1和SMPTE ST 2059-2。

This Standard defines:1) A point in time, the SMPTE Epoch, which is used for alignment of all real-time signals referenced in this Standard;2) The alignment of these signals to the SMPTE Epoch;3) Formulae which specify the ongoing alignment of these signals to time since the SMPTE Epoch;4) Formulae which specify the calculation of SMPTE ST 12-1 Time Address values and SMPTE ST 309 date values from SMPTE Profile IEEE 1588-2008 PTP data.Note: Implementers are encouraged to read both SMPTE ST 2059-1 and SMPTE ST 2059-2 as a pair.
