+PR_Now
+======
+
+Returns the current time.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prtime.h>
+
+   PRTime PR_Now(void);
+
+
+Parameters
+~~~~~~~~~~
+
+None.
+
+
+Returns
+~~~~~~~
+
+The current time as a :ref:`PRTime` value.
+
+
+Description
+-----------
+
+``PR_Now()`` returns the current time as number of microseconds since
+the NSPR epoch, which is midnight (00:00:00) 1 January 1970 UTC.
+
+You cannot assume that the values returned by ``PR_Now()`` are
+monotonically increasing because the system clock of the computer may be
+reset. To obtain monotonically increasing time stamps suitable for
+measuring elapsed time, use ``PR_IntervalNow()``.
