My logstash version is 2.0.0,working in Suse 11SP3。  
when I use command 'date -s "20170923 07:51:09' change system time to year 2024,  
logstash agent is working fine.  
But if I use 'date -s "20160923 07:51:09' change time back .  
logtash agent is not working .  
I kill logstash agent process and then restart , it work fine again.

But if I use Ctrl+c to quit ,show errors:  
["INFLIGHT\_EVENTS\_REPORT", "2024-07-20T07:51:26+08:00", {"input\_to\_filter"=\>0, "filter\_to\_output"=\>0, "outputs"=\>[]}] {:level=\>:warn}  
Received shutdown signal, but pipeline is still waiting for in-flight events  
to be processed. Sending another ^C will force quit Logstash, but this may cause  
data loss. {:level=\>:warn}

Is anybody know this condition?waiting for help ,Thanks~
