Family operator strategies

Operator overload	Strategy	Purpose	Membership scope	Source description
<(abstime,abstime)	1	search	Family member	less than
<=(abstime,abstime)	2	search	Family member	less than or equal
=(abstime,abstime)	3	search	Family member	equal
>=(abstime,abstime)	4	search	Family member	greater than or equal
>(abstime,abstime)	5	search	Family member	greater than
