> Functions about time such as utc_usec_to_second(), utc_usec_to_minute(),
> utc_usec_to_hour(), utc_usec_to_day(), utc_usec_to_week(), utc_usec_to_year()
> are popularly used in many applications.
> These functions are useful when we group data with tome intervals.
> For example, utc_usec_to_day() works as follows.
> {noformat}
> tajo> select utc_usec_to_day(1274259481071200);
> 1274227200000000
> {noformat}
> We need to provide these functions by default.
