5. NORMALIZATION
</SectionTitle>
    <Paragraph position="0"> The NLToolset gives a temporal expression an interval representation. The temporal interval currently abides by the time standard of the original temporal expression; however, in future, the temporal interval will be normalized into Coordinated Universal Time (UTC), which is considered the modern implementation of Greenwich Mean Time.</Paragraph>
    <Paragraph position="1">  This time standard is used worldwide and will allow for greater interactivity between databases and within visualization tools.</Paragraph>
    <Paragraph position="2"> The interval representation is stored within an NLToolset structure in its component parts; that is, the year, month, day, hour, minute, and second for the beginning and endpoint of each interval are stored separately. The original values of the text are also stored. This affords flexibility as the NLToolset is applied to various domains. The application requirements can dictate which parts of the time representation will be stored and displayed.</Paragraph>
