+/** \file timespec.c
+ * \brief Functions for working with timespec structures.
+ *
+ * This library aims to provide a comprehensive set of functions with
+ * well-defined behaviour that handle all edge cases (e.g. negative values) in
+ * a sensible manner.
+ *
+ * Negative values are allowed in the tv_sec and/or tv_usec field of timespec
+ * structures, tv_usec is always relative to tv_sec, so mixing positive and
+ * negative values will produce consistent results:
+ *
+ * <PRE>
+ * { tv_sec = 1, tv_nsec = 500000000 } == 1.5 seconds
+ * { tv_sec = 1, tv_nsec = 0 } == 1.0 seconds
+ * { tv_sec = 1, tv_nsec = -500000000 } == 0.5 seconds
+ * { tv_sec = 0, tv_nsec = 500000000 } == 0.5 seconds
+ * { tv_sec = 0, tv_nsec = 0 } == 0.0 seconds
+ * { tv_sec = 0, tv_nsec = -500000000 } == -0.5 seconds
+ * { tv_sec = -1, tv_nsec = 500000000 } == -0.5 seconds
+ * { tv_sec = -1, tv_nsec = 0 } == -1.0 seconds
+ * { tv_sec = -1, tv_nsec = -500000000 } == -1.5 seconds
+ * </PRE>
+ *
+ * Furthermore, any timespec structure processed or returned by library functions
+ * is normalised according to the rules in timespec_normalise().
