Description

Using "cal.set(Calendar.HOUR,0);" when query message before today which may result in :
"org.apache.rocketmq.client.exception.MQClientException: CODE: 208 DESC: query message by key finished, but no message. "
"HOUR" is used for the 12-hour clock.This will cause the start time of the query message to be greater than the creation time of the message.
Implemenations:
Using "HOUR_OF_DAY" instead of "HOUR"."HOUR_OF_DAY" is used for the 24-hour clock.
