I want to build 10-15 real time clocks, which will be installed in different locations.

How can I synchronize the time for all clocks?

As I already mention all clocks will be installed at different locations & no wire or wireless communications between them is possible & also no Internet connection is available.

Using GPS/GPRS modem to synchronize the time will be very costly so I need some low cost option if possible

Can you tell what'll be the approximate distance between the clocks??Please tell your application in detail.

Hi all,
I think DTMF could be a solution if network is available.You can buy a mobile plan in which all local calls are free.According to me your application is big the cost will also be big you can minimize to an extent only.
