Every workshop needs one of these! This 'Scope clock' uses a microcontroller driven design with a real-time clock back-up.
It can be connected any oscilloscope with an X-Y input (most 2 channel scopes have this capability).
Circuit design and software from Frank Techniek, further details here...
The hardware comprises of an Atmel microcontroller (AtMega8515), a dual DAC, 7805 regulator, and a DS1302 RTC.
Unfortunately, the software does not support DCF77 decoding (Europe's atomic radio clock) due to the limited program memory.

I've also found another interesting Scope Clock kit design, by Jan de Rie.
