-Time math is only done on the \code{psTime} TAI type.
+Time math may only be done on the \code{psTime} TAI type, and so the
+functions shall internally convert the \code{psTime} inputs to TAI
+before performing the math.  The type of the time returned by
+\code{psTimeAdd} shall be the same as that of the input \code{time}.
