+PR_TicksPerSecond
+=================
+
+Returns the number of ticks per second currently used to determine the
+value of :ref:`PRIntervalTime`.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prinrval.h>
+
+ PRUint32 PR_TicksPerSecond(void);
+
+
+Returns
+~~~~~~~
+
+An integer between 1000 and 100000 indicating the number of ticks per
+second counted by :ref:`PRIntervalTime` on the current platform. This value
+is platform-dependent and does not change after NSPR is initialized.
+
+
+Description
+-----------
+
+The value returned by ``PR_TicksPerSecond()`` lies between
+``PR_INTERVAL_MIN`` and ``PR_INTERVAL_MAX``.
+
+The relationship between a :ref:`PRIntervalTime` tick and standard clock
+units is platform-dependent. PR\_\ ``PR_TicksPerSecond()`` allows you to
+discover exactly what that relationship is. Seconds per tick (the
+inverse of PR\_\ ``PR_TicksPerSecond()``) is always between 10
+microseconds and 1 millisecond.
