> Serega Shepak pointed out that something like
> {code}
> select cast(date_occurrence as timestamp) from xvlr_data limit 10
> {code}
> where  date_occurrence has BIGINT type (timestamp in milliseconds) works. But it doesn't work if the declared type is TIMESTAMP on column. The data in the date_occurence column in unix timestamp in millis.
