Time is an important parameter for space-acquired measurements, in virtue of the basing of instrument analysis on a sampled sensor time series. In addition, time provides the most efficient linkage between instrument data and externally generated ancillary parameters. Attention is presently given to the rationale and form of the standard timecode structure developed by NASA, with emphasis on the important class of binary unsegmented codes. The structure provides a mechanism for the self-documentation of timecodes, so that data users can interpret time measurement in an unambiguous manner. The binary unsegmented codes are modular and easily machine-readable; they also feature expendable resolution and ambiguity periods.
