-                seeks to the beginning of the journal, i.e. the oldest
-                available entry.</para>
-
-                <para>Similarly,
-                <function>sd_journal_seek_tail()</function> may be
-                used to seek to the end of the journal, i.e. the most
-                recent available entry.</para>
-
-                <para><function>sd_journal_seek_monotonic_usec()</function>
-                seeks to the entry with the specified monotonic
-                timestamp,
-                i.e. <constant>CLOCK_MONOTONIC</constant>. Since
-                monotonic time restarts on every reboot a boot ID
-                needs to be specified as well.</para>
-
-                <para><function>sd_journal_seek_realtime_usec()</function>
-                seeks to the entry with the specified realtime
-                (wallclock) timestamp,
-                i.e. <constant>CLOCK_REALTIME</constant>. Note that
-                the realtime clock is not necessarily monotonic. If a
-                realtime timestamp is ambiguous, it is not defined
-                which position is sought to.</para>
-

-                <citerefentry><refentrytitle>sd_journal_get_cursor</refentrytitle><manvolnum>3</manvolnum></citerefentry>. If
-                no entry matching the specified cursor is found the
-                call will seek to the next closest entry (in terms of
-                time) instead. To verify whether the newly selected
-                entry actually matches the cursor, use

-
-                <para>Note that these calls do not actually make any
-                entry the new current entry, this needs to be done in

-                invocation (or a similar call). Only then, entry data

-                no entry exists that matches exactly the specified
