Timestamp with Timezone

[Odin Guillermo Caudillo Gallegos]

Hi, i'm getting some errors when trying to do a TO_TIMESTAMP
The string is: 'Oct 19 2015 05:41:46 CDT'
But if i use: TO_TIMESTAMP(EVENT_TIMESTAMP,'Mon DD YYYY HH24:MI:SS TZ'
It's giving me the following error:
2015-10-22 18:16:40,834 ERROR org.apache.tajo.worker.TaskImpl: "TZ"/"tz"
format patterns are not supported in to_date


Thanks
