There are many of those. Just google for WWVB simulator.
Interestingly, there seem more DCF77 simulators out there than
WWVB ones. 

As Clint wrote, be carefull not to emit too much. Transmit only
as much power that your clocks can just barely receive it.
Which probably means not to connect any wire at all.

60kHz is low enough that it will pass through all but steel reinforced
concrete like through air and thus you will probably jam all sourounding
houses/clocks as well.

The same is also true for repeaters, btw.
