[time-nuts] My Custom GPS clock

[Christopher Quarksnow]

Hello, Bert -

 Not having that much experience, I am wondering whether I could retrofit
their DE-DP22811 http://www.sureelectronics.net/goods.php?id=1164 to make an
8 digits clock having 1/100s:
 23 59 59 99
Based in NYC and ideally I would feed it UTC reference, either by GPS minus
15 seconds (as leap seconds are likely to be dropped) or any other source. I
only need 1/100 s accuracy, might even drive from power line.
I'd be glad to pay someone to implement. I have Paypal. The closest thing I
found was a director's clock, yet frames from 0 to 24 instead of hundreds of
seconds from 0 to 99.

Thanks,
Christopher
