Etymology: "Runtimes" is the plural of "runtime", a compound of "run" and "time" that originally meant the length of time something runs. Its computing sense, the period during which a program is executing, grew out of that plain meaning, and the plural form simply counts separate instances of it: the runtimes of several programs, or the different execution environments a single program can be built to use.

Synonyms: execution times, operating times
