In this test, nTime is used for all the calls to Mine(), each time being set to the correct time beforehand, except for in the last few calls to Mine() where nStartTime is used directly, even though nTime is still set to nStartTime beforehand. nTime just remains unused for these last few calls to Mine().
Changed the last few calls to Mine() to use nTime instead, improving consistency. This also fixes an unused value static analyzer warning about nTime being set to a value which is never used.
