  29  <P> The hour scale has more builtin formatting possibilities. The
  30   following formatting options are available</P>
  31  <OL>
  32  <LI> &quot;HOURSTYLE_HM24&quot;, Will display the only the hour in military time
  33   0-24 , for example 13:00</LI>
  34  <LI> &quot;HOURSTYLE_H24&quot;, Will display the hour with both hour and minute in
  35   military time 0-24, for example 13</LI>
  36  <LI>&quot;HOURSTYLE_HMAMPM&quot;, Will display the hour and minutes with a
  37   suitable am/pm postfix, for example 1:30pm</LI>
  38  <LI> &quot;HOURSTYLE_HAMPM&quot;, Will display only the hour with a suitable am/pm
  39   postfix, for example 1pm</LI>
  40  <LI>&quot;HOURSTYLE_CUSTOM&quot;, Custom defined format as specified with a call
  41   to HeaderProperty::SetFormatString()</LI>
  42  </OL>
  43  <P> For hours it is possible to specify the interval in either of two
  44   ways. With an integer, e.g. 6, or as time interval, e.g. &quot;1:30&quot; which
  45   makes the interval one and a half hour. The only restriction is that
  46   the interval must be even dividable for 24 hours since one day is the
  47   smallest possible interval to show. This means that it is allowed to
  48   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>
