Dear Brijesh,
I am Raman(one of the satisfied user of Attend), whatever u have asked about overtime calculation, i am just trying to explain how will u do that,
First of all, u have to go in Attendance module, now u have to open 'Attendance setting' under this module, in which u'll see that there is a lots of attendance setting options, out of them one option u'll find about overtime setting i.e.
"If the employee works outside the planned hours, mark the time slot as 'Overtime'"
and now u have to simply tick this option.
This option works with the system defined attendance type, 'Overtime'. If this option is set, employees working outside planned hours will be marked with the attendance type 'Overtime'.
Hope this helps..
