Pythagorean tuning in more detail Originally I was tempted to label this section "Mathematical aspects of Pythagorean tuning," but decided that such a title might discourage some readers mainly interested in practical details of implementing this tuning on various instruments ranging from medieval harps to organs and electronic synthesizers.

Practical relevance[ edit ] Five-digit years are already a problem today for many forward-looking analysis programs e. Examples[ edit ] This problem can be seen in the spreadsheet program Microsoft Excel through at least its Office release, which stores dates as the number of days since 31 December day 1 is ; similarly, Microsoft Access stores dates as the number of days since 30 December day 1 is In either application, a date value of will be correctly formatted as "31 December ", but adding 1 to that to step over to the expected date of "1 January " will cause a formatting error; in Excel, for example, it will be displayed in the cell as a series of characters.

The Long Now Foundation ran into this limitation of Excel during the design of the 10, year clock. The GNU Fortran compilerg77makes reference in runtime environment limits to year 10, Y10K problems when using intrinsic functions with this compiler suite.

The problem is simply stated as, "Most intrinsics returning, or computing values based on, date information are prone to Year, Y10K problems, due to supporting only 4 digits for the year. For example, the date might appear, to such programs, to wrap around change from a larger value to a smaller one as of the Year PHP 's DateTime class can handle five-digit years, except for parsing date strings with e.

Problems with data representation[ edit ] Unlike the Year problemwhere significant digits were omitted from the stored values of years, fixing the Year 10, problem does not require updating old records assuming they are already Y2K-compliantsince all four significant digits are present.

It only requires that record storage in decimal be able to store five or more digits. There is, however, a potential problem with record sets that make use of lexical sorting. For example, representations of dates in the range 10,—19, would appear interlaced with dates in the range — rather than after the year Mitigation[ edit ] The Long Now Foundation is attempting to foster the custom of writing years with five digits, so that the year would be written as "".

This would preempt the Year 10, problem, but would in turn be susceptible to the "Yearproblem".In western Europe the European Commission issued a report warning that efforts to solve Y2K in many European Union member countries were insufficient, particularly in terms of the cross-border cooperation needed to be ready by The British government announced that its armed forces would be prepared in time and would provide assistance to local police if utilities, transportation systems, or emergency .

By now, everyone has heard of the "Year bug," caused by computer programs that use only the last two digits of any given year to represent the date. In the new millennium, when the year is shortened to "00," most computer programs and applications will interpret the year as , not hence the problem.

The Year problem, also known as the Y2K problem, the Millennium bug, the Y2K bug, or Y2K, is a class of computer bugs related to the formatting and storage of calendar data for dates beginning in the year Problems were anticipated, and arose, because many programs represented four-digit years with only the final two digits — making the year indistinguishable from Downmarket media publications reflect - and exaggerate - many of the fears of society itself.
