+    <para>Note that timestamps printed by systemd will not be parsed
+    correctly by systemd, as the timezone specification is not
+    accepted, and printing timestamps is subject to locale settings
+    for the weekday while parsing only accepts English weekday
+    names.</para>
+
+    <para>In some cases, systemd will display a relative timestamp
+    (relative to the current time, or the time of invocation of the
+    command) instead or in addition to an absolute timestamp as
+    described above. A relative timestamp is formatted as
+    follows:</para>
+
+    <para>2 months 5 days ago</para>
+
+    <para>Note that any relative timestamp will also parse correctly
+    where a timestamp is expected. (see above)</para>

+    <title>Calendar Events</title>
+
+    <para>Calendar events may be used to refer to one or more points
+    in time in a single expression. They form a superset of the
+    absolute timestamps explained above:</para>
+
+    <programlisting>Thu,Fri 2012-*-1,5 11:12:13</programlisting>
+
+    <para>The above refers to 11:12:13 of the first or fifth day of
+    any month of the year 2012, but only if that day is a Thursday or
+    Friday.</para>
+
+    <para>The weekday specification is optional. If specified, it
+    should consist of one or more English language weekday names,
+    either in the abbreviated (Wed) or non-abbreviated (Wednesday)
+    form (case does not matter), separated by commas. Specifying two
+    weekdays separated by <literal>-</literal> refers to a range of
+    continuous weekdays. <literal>,</literal> and <literal>-</literal>
+    may be combined freely.</para>
+
+    <para>In the date and time specifications, any component may be
+    specified as <literal>*</literal> in which case any value will
+    match. Alternatively, each component can be specified as a list of
+    values separated by commas. Values may also be suffixed with
+    <literal>/</literal> and a repetition value, which indicates that
+    the value and all values plus multiples of the repetition value
+    are matched.</para>
+
+    <para>Either time or date specification may be omitted, in which
+    case the current day and 00:00:00 is implied, respectively. If the
+    second component is not specified, <literal>:00</literal> is
+    assumed.</para>
+
+    <para>Timezone names may not be specified.</para>
+
+    <para>The special expressions
+    <literal>minutely</literal>,
+    <literal>hourly</literal>, <literal>daily</literal>,
+    <literal>monthly</literal>, <literal>weekly</literal>,
+    <literal>yearly</literal>,
+    <literal>quarterly</literal>,
+    <literal>semiannually</literal> may be used as
+    calendar events which refer to
+    <literal>*-*-* *:*:00</literal>,
+    <literal>*-*-* *:00:00</literal>,
+    <literal>*-*-* 00:00:00</literal>,
+    <literal>*-*-01 00:00:00</literal>,
+    <literal>Mon *-*-* 00:00:00</literal>,
+    <literal>*-01-01 00:00:00</literal>,
+    <literal>*-01,04,07,10-01 00:00:0</literal> and
+    <literal>*-01,07-01 00:00:00</literal> respectively.
