Anybody no idea?

new attach file.

help me. plz

The line with time picker controls defines as part of
scheduler.form_blocks.time
And it can be modified only by changes in dhtmlxscheduler.js

You can check debug version of js files ( it will be around line 3250 ) - you will need to alter render method, which defines HTML of the control
