Need help writing SQL statement - Mailing list pgsql-general

I have been trying to write an sql statement that returns the same hours
in a time stamp no matter what the date.
I can to pull same hours on the the same days but have not been able to
figure out how to pull all the same hours no matter what the date.

Here is the one sql statement I have been using:
SELECT COUNT(time_stamp) FROM table WHERE time_stamp BETWEEN
20050629100000 and 20050631100000;

Any help would be appreciated.

Thanks in advanced for any help
