<h1>KTimeZoneData Class Reference</h1>

<p>
<h2>Detailed Description</h2>
<p>Base class for the parsed data returned by a KTimeZoneSource class.
</p>
<p>
It contains all the data available from the KTimeZoneSource class,
including, when available, a complete list of daylight savings time
changes and leap seconds adjustments.
</p>
<p>
This base class can be instantiated, but contains no data.
</p>
<p>
Base class for parsed time zone data
