ITime Interface

Provides access to members that control the Time.

Description

The ITime interface is used to access a scalar time value.  There is no associated temporal reference, so there is no time zone or daylight savings time associated with the value.  The ITime interface can be used to do simple conversions, such as setting a year, month and day, then getting querying for a Julian Day number.  The ITime interface supports values with nanosecond accuracy.  In general, setting individual values such as the year, month, and day can be problematic.  for example, if the Month is set to 2 (February) when the day already has the value 31, this will cause an error because there is no February 31st.  It would be better to set the month and day at the same time.
