Select "Model|MODFLOW Time..." and enter the following data for the 127 stress periods. The easiest way to do this is to enter 0 and 10 for the starting and ending times, 10 for the length, 10 for the maximum first time step length, and Transient. Then change the number of stress periods to 127. You could also copy the following text and paste it into the table in the MODFLOW Time dialog box.
