hi guozhang,
i mean ,in a certain topic ，can i use the offset compute the msg's time
stamp(when the msg produced)？
in fact， i need an api look like:
setOffset(String topicId ,String groupId, long timeStamp){
}
this method can be call by the comsumer ，and then the offset will be reset.
after call this method,the comsumer only comsume the msg occur after the
timeStamp.
i am very sorry .I do not specify whether I describe clearly.

Hello,
I do not fully understanding your question, did you mean that you want to know
when a message with certain offset is produced?

Hi all,
we have a scene like this:
A system produce the msg ,B system comsumer the msg.
for some reason the B system unwork,and then we need abandon the out of date
msg.
but now in our msg there is no time stamp.
how can i use the offset to do this.
does kafka know when the msg produce?
how can i location the certain offset?
thanks
