+PRTime
+======
+
+A representation of absolute times.
+
+
+Syntax
+------
+
+.. code::
+
+    #include <prtime.h>
+
+    typedef PRInt64 PRTime;
+
+
+Description
+-----------
+
+This type is a 64-bit integer representing the number of microseconds
+since the NSPR epoch, midnight (00:00:00) 1 January 1970 Coordinated
+Universal Time (UTC). A time after the epoch has a positive value, and a
+time before the epoch has a negative value.
+
+In NSPR, we use the more familiar term Greenwich Mean Time (GMT) in
+place of UTC. Although UTC and GMT are not exactly the same in their
+precise definitions, they can generally be treated as if they were.
+
+.. note::
+
+   **Note:** Keep in mind that while :ref:`PRTime` stores times in
+   microseconds since epoch, JavaScript date objects store times in
+   milliseconds since epoch.
