Super pi days

In just a few years we will have: 3/14/15 9:26:53.58 and 16 years later: 31/4/15 9:26:53.58 - which in the US will also be Income Taxes due Day X|

OK, US dates with their ridiculous ordering of units has always done my head in, but I now offocially give up. How is 14 Mar 2015 (or is that 3 (Jan++)++ 2015?) 16 years behind 31 Apr 2015? Oh, you mean 15 Apr 2031? :doh: This is why is should be a flogging offense not not have dates formatted unambigously. small->large, or (full digits) large -> small, or dd MMM yyyy is even better.

Yes, yyyymmdd is the easiest to sort (date treated as an integer number) and mmddyyyy or ddmmyyyy is much more difficult :sigh: - In a Genealogy course I took in college we were told to write dates at dd-MMM-yyyy so there is no ambiguity :thumbsup: ... but then us Math guys are notorious for fiddling with the digits to get the desired results ;)

Not to say that April does not have a 31st day.

I wonder why we just not count the days, how difficult it may be? For example today is 734456 AD. And of course the negative numbers will represent BC.

Just bag all that. Track all time values in Ticks. It's clearly the best solution, no formatting worries there. :thumbsup:

Why not seconds? Right now is something like 63,456,998,400 AD. :)

If the US wants to biggie-size April then it's not something that would surprise me

In my workplace, we use yyyymmdd for comments, file naming, etc.. it's damn easy to sort. I have always felt that mmddyy is just irrational. You don't say a player finished a race in 23 mins 45 secs 1 hour. That's just ridiculous.
Peace, ye fat guts!
Perhaps what we need is to use the 'Time Police'. They could rigorously enforce stamdards across the world. Nay even acroos TIME itself. Question is do we A) Create the Time Police ourselves or B) Wait for their creation in the future. With Time Travel they cna travel back to our 'time' to Retro Enforce Time Standards Regrads The Retro-Enforcer

Read the discussions on date micro formats for HTML5 (sorry, I haven't got a link - I am sure that another CPian will be able to find some). Genealogies is cited as a difficult case as the dates go before 1752. The recommendation (in the microformats discussions) is that you still use the Gregorian dates, but that would be very confusing as the historical dates were Julian (which I am sure is what most genealogy courses would use). Also, genealogies hit one of the other date format 'gotchas': approximations; how do you represent 'sometime probably in September between 4BC and 1AD'?

No you don't. But it is more common to say "It is ten past eleven", than to say "It is 11 o'clock plus ten minutes". Admittedly, "It is 11:10" is quicker. Posted just after ten past eleven, GMT.

07/20/2069 19:37:33 will be unix timestamp 3141592653 other notable timestamps: time of the beast (unix timestamp 666) was 12/31/1969 19:11:06 Euler time (unix timestamp 2718281828) will be 02/20/2056 09:17:08 AM avagadro's time overflows a 64 bit int... so don't hold your breath and PHI time (unix timestamp 1618033988) is 04/10/2021 01:53:08 AM

I first convert the Gregorian date to the Julian Day Count, make the calculated adjustment, then convert back to the Gregorian or Julian calendar. While this may seem an extra step in the process, it does have two advantages. 1. The dates remain in their numerical sequence and thus allow for accurate sorting. 2. Regardless of the calendar you convert back to, Gregorian or Julian, the date will be accurate within a 12 hour period. The one draw back to the JDC is that the JDC changes at noon rather than midnight. This could be rectified by creating a new day count that starts at midnight rather than noon. Scott A. Tovey

Obviously this only occurs in the US, in Europe with dd/mm/yy we get any early pi on March the 14th in 2015 So guess you have to refer to 3/14/15 as American pie :)

So guess you have to refer to 3/14/15 as American pieHere in the US, most of us grow up using the dd/mm/yy format. The only ones who use that other format are the ones who need people to think that they are smart. They're insecure because of the increasing forgetfulness that they have been experiencing. Do you think we should tell them that's called "getting old"? Just one thing: What were we talking about? :laugh: Scott
