Birthday Presents, part 1

[tithonium]

So, something I would like for my birthday, and I mention it now, since it'll take some development time.

A clock. No, really, two clocks.

The first, perfectly normal analog 24 hour clock. When it hits 24:00:00, it stops. For 2375 seconds. Then starts again.

The second, probably more complicated, perfectly normal analog 24 hour clock. When it hits 24:00:00, the minute and second hands keep going, but the hour hand stops moving. It doesn't crawl along like normal. When the minute+second hit --:39:34, they swing back to vertical so that what would have been --:39:35 is 00:00:00, and things resume as normal, with the hour hand sweeping slowly along as the minutes move forward.

Electric, or mechanical? Battery or line-powered?

Not that picky. I'd prefer battery, but whatever.

That would be... very hard.

...or it would be really easy (cash-soluble).

That's not a time-slip clock. That's a longer-second clock. It runs about 97.324% as fast as a standard clock.

So you want a clock that can't keep Earth time, can't keep Martian time to an accuracy greater than one sol, and can only be used as a stopwatch?

I think the point is that is how time was kept in those Mars books . . . or so I vaguely recall (or was that a different story?). Essentially one creates a phantom partial-hour at midnight, much like the daylight savings time phantom full hour in the fall. (How does that get officially handled, timestamp-wise?)

Seems one would want some indication that the minute/second hand were working through the phantom partial-hour and not the start-of-the-next day 00: hour.
