Class TTimeIntervalBase

class TTimeIntervalBase;

Description

Provides a base class for all time interval classes using a 32-bit representation.

It supports retrieving the interval and provides various operations for comparing intervals. Its concrete derived classes can be added to and subtracted from a TTime.

The comparison operators simply compare the integer representations of the two intervals. They do not take account of different time interval units. So, for example, when comparing for equality an interval of three hours with an interval of three days, the result is true.
