DateTimeType vs. DateType

[Mark W. Alme]

Hello:

        I was having trouble using DateTypes:
<code>
        ULong seconds = TimGetSeconds();

        DateType date;
        DateSecondsToDate(TimGetSeconds(), &date);
        // date now 4 years prior to current date

        ULong addSeconds = (4 * 365.25 * 24 * 60 * 60); // add four years
        seconds += addSeconds;
        DateSecondsToDate(seconds, &date);
        // date now current day of the year 100 (when current date in 2000)
        // is this some sort of y2k problem?

        // using DateTimeType seems to fix the problem
        DateTimeType timer;

        TimSecondsToDateTime(TimGetSeconds(), &timer);
         // timer now has correct current date.

</code>

        Does anyone know if there is a know advantage for using 
DateTimeTypes versus using DateTypes?  I saw a post on the archives 
where a developer wondered if DateTypes even existed in the api. 
Advice welcome.
