- realtime (wallclock) timestamp of the current journal entry. It

- is in microseconds since the epoch, i.e.
- <code class="constant">CLOCK_REALTIME</code>.</p><p><code class="function">sd_journal_get_monotonic_usec()</code> gets
- the monotonic timestamp of the current journal entry. It takes
- three arguments: the journal context object, a pointer to a 64-bit
- unsigned integer to store the timestamp in, as well as a 128-bit
- ID buffer to store the boot ID of the monotonic timestamp. The
- timestamp is in microseconds since boot-up of the specific boot,
- i.e. <code class="constant">CLOCK_MONOTONIC</code>. Since the monotonic
- clock begins new with every reboot, it only defines a well-defined
- point in time when used together with an identifier identifying
- the boot. See
- <a href="sd_id128_get_boot.html"><span class="citerefentry"><span class="refentrytitle">sd_id128_get_boot</span>(3)</span></a>
- for more information. If the boot ID parameter is passed
- <code class="constant">NULL</code>, the function will fail if the monotonic
- timestamp of the current entry is not of the current system
- boot.</p><p>Note that these functions will not work before
