Zusammenfassung:This paper describes some of the design considerations behind the timescale transformation software provided by the International Astronomical Union's SOFA collaboration. The solution adopted by SOFA includes two-part Julian dates, to safeguard precision, and individual treatment of specific transformations, rather than a single general-purpose routine. Correct handling of UTC leap seconds was a particular challenge. [PUBLICATION ABSTRACT]
