+This module provides various time-related functions. It is always
+available, but not all functions are available on all platforms. Most
+of the functions defined in this module call platform C library
+functions with the same name. It may sometimes be helpful to consult
+the platform documentation, because the semantics of these functions
+varies among platforms.
An explanation of some terminology and conventions is in order.
