public class CDate
extends java.lang.Object

Clarion date format is number of days since Dec 28 1800. --------------- Valid values start from 4 , Jan 1 1801. Epoch (1.1.1970) = 61730 Assumption is that clarion stored date is localtime based on current timezone location - so epoch conversion will take this into consideration i.e. 1.1.1970 clarion date for me equals 1.1.1970 Midnight Melbourne/Victoria But for someone running software in different TZ, the epoch result will differ Clarion time format --------------- Value = 100ths of seconds since midnight + 1. i.e. midnight = 1 the 100th of a second before midnight = 8640000 Assumption is that clarion time values are wall time only and do not take daylight savings variations into consideration
