URGENT HELP

I'm currently undergoing my training at a well known company.I have been assigned with a hardware project. Here is the description of the project:

I need to create a circuit that will switch ON automatically at a time fixed by the company.For example since the company starts operation at 8am, the machine must switch ON automatically at that time.Then it will OFF automatically at 5pm. I have to install this additional circuit to a machine.

If anybody is willing to help,please provide me your e-mail address as soon as possible.Please help as I need the circuit urgently.

Your cooperation is highly appreciated....Thank you.

Do you want to build a timer ? Or are you looking for a commercially available one ?

If your talking 120 volts AC, the timers at the link below are the ones ive installed for customers to control on-off timing for lighting and they're quite cheap.

Before you do too much work i highly sugest that you cheack the electrical code to make sure that the device you want to autostart is permited to self start by code. Also be sure you have a manual clock override (ie you dont want that plant starting and running all night on a holiday weakend when no one is around)

Im not sure what resources you have available on this project but the simple industrial solution is to use a PLC.
