Rube Goldberg Code

Wow, walk away from including years. Leap years will quickly turn this into Monty Python level silliness.

Hmm, I wonder if that's why they started the seconds at 1904.

Yes, because it meant you only have to check for divisibility by 4 and you're good up to 2096 (2000 was a leap year because it's divisible by 400). This was a relevant consideration when the format was designed, probably somewhere in the 70's or early 80's.

horology lesson.  (Yes I have made an amature study of horology- please don't tell my wife)  1900 was significant in timekeeping because between 1950 and 1960 The SI second was defined as: "The fraction 1/31,556,925.9747 of the tropical year for 1900 January 0 at 12 hours ephemeris time"  This definition has remained adopted by various programs for the keeping of civil time.  Since 1960 the SI Second was redefined to be consistant with atomic clocks: "The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom."  The differences introduced by severing planatary motion for civil timekeeping and Atomic activity for scientific instrumentation are resolved by leap seconds inserted or deleted as needed in order to synchronize astronomical observation with time to within a 1/2 second or so (they are inserted or deleted on prefered days).

the 1904 Epoch is the one apple chose as a base date for its OS.  So chosen by fiat with the justification that it was the first leap year on the 20th centuary thus ensuring that leap years could be calculated as year mod 4 R=0 until the year 2100.

Now that leap years are sorted... we need to make it leap-second proof.

Hence the Time to Time of day function.  Leap seconds are recorded at the residence of Vice President Biden.  Just give Joe a call and ask for a lookup table.

And here I thought all of this was created and handled by the Former Future President of United States All Gore...

OK, I am stumped. The second frame of a huge sequnce contains only the following code. What is it supposed to do??? 😄

(looks like a simple 200ms delay ...)

It's a genius way of implementing a wait function!

Maybe we should suggest to turn the diagram constant into a control and then make the entire thing into a subVI. 😄
