-      <para><varname>TimeoutStartUSec</varname>, <varname>TimeoutStopUSec</varname> and

-      <citerefentry><refentrytitle>systemd.service</refentrytitle><manvolnum>7</manvolnum></citerefentry>):
-      these bus properties strictly use microseconds (and thus are suffixed <varname>…USec</varname>) while
-      the unit file settings default to a time unit of seconds (and thus are suffixed
-      <varname>…Sec</varname>), unless a different unit is explicitly specified. This reflects that fact that
-      internally the service manager deals in microsecond units only, and the bus properties are a relatively
-      low-level (binary) concept exposing this. The unit file settings on the other hand are relatively
-      high-level (string-based) concepts and thus support more user friendly time specifications which
-      default to second time units but allow other units too, if specified.</para>
