> The Timing Subsystem is a central timing facility for the ARIA electronic system. Its primary function is to generate time codes and precision pulse repetition rates which are recorded with the data to allow for time correlation in interpreting spacecraft events when the tapes are processed. In addition, the subsystem provides each equipment operator with displays of Coordinated Universal Time (UTC)
Oh wow, crazy: in 1969, the UTC time would have been a negative number!
- euler_angles 7y agoNo, you're thinking of the UNIX epoch. UTC began in the early 1960s. https://en.wikipedia.org/wiki/Coordinated_Universal_Time https://en.wikipedia.org/wiki/Coordinated_Universal_Time The IRIG standards for time codes also date to around this time.
- danaliv 7y agoUTC != Unix time. UTC is a standard by which time is measured, independent of any particular representation. Unix time is one way of representing or encoding a given point in time.
