+
+        This parser will parse a time interval specification into a ClockService::clock_type
+        value. The following units are supported:
+
+        <table class="senf fixedcolumn">
+        <tr><td>\c d</td><td>days</td></tr>
+        <tr><td>\c h</td><td>hours</td></tr>
+        <tr><td>\c m</td><td>minutes</td></tr>
+        <tr><td>\c s</td><td>seconds</td></tr>
+        </table>
+
+        Additionally, the unit may be prefixed by an SI scale:
+
+        <table class="senf fixedcolumn">
+        <tr><td>\c m</td><td>milli</td></tr>
+        <tr><td>\c u</td><td>micro</td></tr>
+        <tr><td>\c n</td><td>nano</td></tr>
+        </table>
+
+        An optional decimal point is also supported. A single timer interval may combine any number
+        of these specifications. The following are all valid intervals:
+
+        <table class="senf fixedcolumn">
+        <tr><td><code>10d</code></td><td>10 days</td></tr>
+        <tr><td><code>5d5d</code></td><td>10 days</td></tr>
+        <tr><td><code>1d2h100m3.5s</code></td><td>27 hours, 30 minutes and 3.5 seconds</td></tr>

+        <tr><td><code>1.1s</code></td><td>1.1 seconds</td></tr>
+        <tr><td><code>123.456us</code></td><td>123.456 microseconds</td></tr>
