<P> The hour scale has more builtin formatting possibilities. The
 following formatting options are available</P>
<OL>
<LI> &quot;HOURSTYLE_HM24&quot;, Will display the only the hour in military time
 0-24 , for example 13:00</LI>
<LI> &quot;HOURSTYLE_H24&quot;, Will display the hour with both hour and minute in
 military time 0-24, for example 13</LI>
<LI>&quot;HOURSTYLE_HMAMPM&quot;, Will display the hour and minutes with a
 suitable am/pm postfix, for example 1:30pm</LI>
<LI> &quot;HOURSTYLE_HAMPM&quot;, Will display only the hour with a suitable am/pm
 postfix, for example 1pm</LI>
<LI>&quot;HOURSTYLE_CUSTOM&quot;, Custom defined format as specified with a call
 to HeaderProperty::SetFormatString()</LI>
</OL>
<P> For hours it is possible to specify the interval in either of two
 ways. With an integer, e.g. 6, or as time interval, e.g. &quot;1:30&quot; which
 makes the interval one and a half hour. The only restriction is that
 the interval must be even dividable for 24 hours since one day is the
 smallest possible interval to show. This means that it is allowed to
 use, for example 2,4,6,&quot;1:30&quot; or &quot;0:45&quot; as intervals but not 7, &quot;2:45&quot;.</P>
<P> The code snippet below shows hot to set up a hour scale to with 45
