推荐答案
您将创建一个新的REQUEST，其RECURRENCE-ID与28号的原始实例dtstart时间相对应，而DTSTART与新的datetime.
You would create a new REQUEST with a RECURRENCE-ID corresponding to the original instance dtstart time for the 28th and a DTSTART with the new datetime.
...
BEGIN:VEVENT
RECURRENCE-ID: 20160728T073000Z
DTSTART: 20160728T073000Z
DTEND: 20160728T083000Z
SEQUENCE: 1
