If:
(a) for any purpose (for example, the purposes of a law, agreement or instrument) an act must or may be done within a particular period or before a particular time; and
(b) this Division, or Division 5 or 6, prevents the act from being done within that period or before that time;
the period is extended, or the time is deferred, because of this section, according to how long this Division, or Division 5 or 6, prevented the act from being done.
