Re^2: Calculate clock ticks since a given date

I have a Grandfather clock that ticks once every 2 seconds, (and tocks every two on the alternate second). But it also looses around 30 minutes a day.

Nothing wrong with the clock ... it's just that time itself now runs faster than it did when the clock was built ;-)

You could compensate for this by shortening the periodicity of the pendulum ?

Cheers,
Rob

Ain't that the truth!

We could but for that long before it was bequeathed to us, someone broke the adjustment -- looks like they stripped the thread trying to turn the rusted on nut with pliers or similar -- and 'fixed' it by braising the nut in place.

These days it's kept -- unwound; the ticks and tocks and whirs and clunks would give the dead a bad night -- purely for its sentimental and decorative value.

(And more of the former than the latter in my opinion, but it wasn't bequeathed from my side of the family, so I don't get much say in the matter :)

You could adjust the height of the weight by horseshoe shimming between brazed nut and weight to shorten the stroke.Unless of course they brazed nut to weight

 [LanX]: ... so my boss started a project with the newest sun servers and invited the traders to come on weekend to test it... and they were so pleased, that they forced him to keep it in production... [ambrus]: Corion: sure, this is the long-term plan. The short term is that I have to run this ungodly mess to get results from the new input data today. [Corion]: ambrus: Most of our "automation" is tied to process exit codes and a shell pipeline :-\ [LanX]: ... a week later they realized that one of the databases - which recorded how much the other banks due to this bank - was not correctly plugged [ambrus]: Corion: I have no problem with exit codes and shell pipeline. My problem is that the current process requires a lot of manual intervention from me, including editing the source codes. [ambrus]: (Also a lot of manual intervention by two or three other co-workers, who do other parts of the process.) [ambrus]: Some of the manual part is unavoidable, but not all. [choroba]: LanX was there a way to recover the numbers from the remaining information? [Corion]: LanX: Ow ;)
