(2) If a document specifies a delayed effective time and date, the document becomes effective at the time and date specified. If a document specifies a delayed effective date but no time, the document becomes effective at 12:01 a.m. on that date. A delayed effective date for a document may not be later than the 90th day after the date the document is filed. [1987 c.52 §7; 1989 c.1040 §4; 2019 c.325 §19]
