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.
