> *Given* that input value is "YYYY-MM-DD HH:MM:SS.nnn" type of TIMESTAMP (UNSIGNED_TIMESTAMP, DATE, TIME etc)
> *When* applying TRUNC|ROUND|FLOOR|CEIL with DAY|HOUR|MINUTE|SECOND|MILLISECOND
> *Than* result should be "YYYY-MM-DD HH:MM:SS.nnn"
> But "YYYY-MM-DD" is returned instead.
> Basically when I do TRUNC on timestamp I would expect it to be timestamp with relevant parts truncated so for example I can GROUP BY on TRUNC (timestamp,'HOUR') and have my hourly aggregation.
> Here is test queries with cast(current_date() AS timestamp).
