unfortunately not in India as our power generation, though grid sync'ed, is not locked to any standard . it is around 47 to 49Hz and clocks configured for 50Hz run slow. we have to have 50 Hz time base, or 1Hz pulse.
there are simpler ways to get it
32.768KHz crystal and two CMOS chips CD40xx give the concerned clock. perhaps we can use a pic and write a small .asm file to output 50Hz and out of phase signals so that the mains wall clocks can be fed these clocks. i once made using 12F510 and 4MHz crystal.
