Note: Intervals always end in ":000". This distinguishes intervals from dates.

Note: Intervals always end in ":000". This distinguishes intervals from

time stamps.

CIMDateTime objects are constructed from String objects or from

other CIMDateTime objects. Character strings must be exactly

twenty-five characters in length and conform to either the date or interval

or interval format.

CIMDateTime objects that are not explicitly initialized will be

implicitly initialized with a zero time interval:

00000000000000.000000:000

The following table shows what arithmetic operations are allowed

between CIMDateTime types. The entries in the last four columns define

the type of the result when the operation, specified in the column header,

is performed on operands, of the types specified in the first two columns.

<PRE>

LHS - left hand side TS - time stamp int - integer

RHS - right hand side IV - interval

The relational operators may only operate on two operands of the same type,

i.e. two time stamps or two intervals.
