Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_29179 ( "Rank" real, "Rider" text, "Sat 21 Aug" text, "Mon 23 Aug" text, "Tues 24 Aug" text, "Wed 25 Aug" text, "Thurs 26 Aug" text, "Fri 27 Aug" text, "Sat 28 Aug" text )

### Question ###
If Wed Aug 25 is no time, what is Sat aug 21?

### Accurate SQL ###

SELECT "Sat 21 Aug" FROM table_29179 WHERE "Wed 25 Aug" = '—— No Time'
