+Description
+-----------
+
+The :ref:`PRExplodedTime` structure represents clock/calendar time.
+:ref:`PRExplodedTime` has the familiar time components: year, month, day of
+month, hour, minute, second. It also has a microsecond component, as
+well as the day of week and the day of year. In addition,
+:ref:`PRExplodedTime` includes a :ref:`PRTimeParameters` structure
+representing the local time zone information, so that the time point is
+non-ambiguously specified.
+
+The essential members of :ref:`PRExplodedTime` are:
+
+ - :ref:`tm_year`: absolute year, AD (by "absolute," we mean if the year is
+   2000, this field's value is 2000).
+ - :ref:`tm_month`: number of months past tm_year. The range is [0, 11]. 0
+   is January and 11 is December.
+ - :ref:`tm_mday`: the day of month. The range is [1, 31]. Note that it
+   starts from 1 as opposed to 0.
+ - :ref:`tm_hour`: number of hours past tm_mday. The range is [0, 23].
+ - :ref:`tm_min`: number of minutes past tm_hour. The range is [0, 59].
+ - :ref:`tm_sec`: number of seconds past tm_min. The range is [0, 61]. The
+   values 60 and 61 are for accommodating up to two leap seconds.
+ - :ref:`tm_usec`: number of microseconds past tm_sec. The range is [0,
+   999999].
+ - :ref:`tm_params`: a `PRTimeParameters` structure representing the
+   local time zone information.
+
+The nonessential members of :ref:`PRExplodedTime` are:
+
+ - :ref:`tm_wday`: day of week. The range is [0, 6]. 0 is Sunday, 1 is
+   Monday, and 6 is Saturday.
+ - :ref:`tm_yday`: day of year. The range is [0, 365]. 0 is the 1st of
+   January.
+
+On input to NSPR functions, only the essential members of
+:ref:`PRExplodedTime` must be specified. The two nonessential members (day
+of week and day of year) are ignored by NSPR functions as input. When an
+NSPR function returns a :ref:`PRExplodedTime` object or sets a
+:ref:`PRExplodedTime` object as output, all of the :ref:`PRExplodedTime`
+members are set, including the nonessential members. You can also use
+``PR_NormalizeTime()`` to calculate the values of the nonessential
+members.
