    Description

      Query 

      select time_format(timediff('15:00:08', '15:01:08'), '%im %ss') as d

      Returns -01m 00s as expected.
      But inside the subquery, the last character is truncated.

      select * from (
      		 
          select time_format(timediff('15:00:08', '15:01:08'), '%im %ss') as d
      		 
      ) t

      Returns -01m 00
