mm = minute (0-59)

ss = second (0-59)

mmmmmm = microseconds

s = '+' or '-' to represent the UTC sign

s = '+' or '-' to represent the Coordinated Universal Time (UTC) sign

utc = UTC offset (same as GMT offset)

An interval has the following form:

time stamps.

Intervals are really durations since they do not specify a start and

end time (as one expects when speaking about an interval). It is

better to think of an interval as specifying time elapsed since

some event.

CIMDateTime objects are constructed from String objects or from

other CIMDateTime objects. These character strings must be exactly

other CIMDateTime objects. Character strings must be exactly

twenty-five characters and conform to one of the forms identified

twenty-five characters in length and conform to either the time stamp

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

X - operation not allowed between types

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

i.e. two time stamps or two intervals.
