How to convert String timestamp to actual timestamp?

Hello All,

I have such kind of syslog events :
Jan 22 14:24:23 mike.local DDP_Agent[83]: Complete - state change from encrypted_state to encrypted_state, commandState = encrypt_commandedState

Once I parse using syslog , I get syslog_timestamp as
"syslog_timestamp" => "Jan 22 14:11:23"

which is a string. How do I convert into timestamp so that I can put this into elastic search and have queries based on timestamp.

Thanks
Gaurav

Please don't start many threads about the same problem. The answer is still that you should use the date filter, which you've successfully done.
