| − | Does nobody realize that March 10th is Mario Day? When you abbreviate march it looks like Mario (MAR10). So, there in fact, is something special about this day. :) [[Special:Contributions/162.158.63.160|162.158.63.160]] 20:59, 11 March 2018 (UTC)

| − | :One hour is duplicated each year at the end of DST. Not much happens during that hour, because it's the middle of the night. A poorly written computer program that instructs the computer to set back the clock one hour whenever the clock reaches a specific time would get caught in a recursive loop (never advancing beyond that time). Properly, clocks are set back one hour when that time is first reached, but are allowed to advance after the duplicate hour concludes.

| − | :Not sure if this in regards to a now missing statement in the Wiki, but the reference in the comic is to days. DST occurs as 2AM, so the day is not repeated. However, 1 - 2 is repeated when time is turned back and 2:01 to 2:59 are ignored when moving ahead. Of course, this assumes one lives in a state that recognizes DST. 15:07, 5 October 2014 (UTC)

| − | Leap second does not result in a duplicate. The additional second is allowed by increasing the number of seconds in a minute. Normally, the 60 seconds of 11:59 are numbered from 11:59:00 to 11:59:59, which is followed by 12:00:00. When there is a leap second, 11:59 has 61 seconds, numbered from 11:59:00 to 11:59:60 (61 total seconds) and then 11:59:60 is followed by 12:00:00.[[Special:Contributions/173.245.48.24|173.245.48.24]] 18:42, 29 March 2014 (UTC)

| − | The problem of the date rolling back is partially mitigated by storing the year as an integer instead of as characters, such as how certain Spreadsheet programs, such as OpenOffice Calc, stores years as a 16-bit signed integer. This doesn't solve the issue, only pushing it back to be the year 32768 problem. This is even less of an issue for 64 bit Unix time, which expire on 15:30:08 UTC on Sun, 4 December 292,277,026,596. It's also important to note that the dates, such as 99, or 00 should not be seen as digits, they should be seen as characters (unless, of course, they are BCD digits, which entirely defeats the purpose of shortening the date to 2 characters length). This might seem trivial, but I think it's an important difference.[[Special:Contributions/108.162.216.41|108.162.216.41]] 02:46, 11 March 2014 (UTC)

| − | :: As a (culturally) dd/mm/[yy]yy person (and ignoring, for brevity, the different options for delimiter), I find yyyy-dd-mm as illogical as mm/dd/yyyy... Why should anybody switch 'precision direction', mid-way? Still, as someone who went through the Y2K process ''and'' worked with colleagues across the Atlantic, I tend to use dd/Mmm/yyyy habitually in "for humans" systems (giving the abbreviated month spelling to avoid all ambiguity, as well as full year-number), or my own "yyyymmdd[-hhmm[ss[.ddd...]]]" format in (informal and internal) programming situations, with comments attached to any conversion routines (inwards and outwards). ((And, yes, there ''are'' ISO/other standards, but I find converting from/to them and internally working with my own long-practiced format works best, for me. YMMV. But be aware of how'd you deal with (or ignore) Leap Seconds!)) [[Special:Contributions/141.101.98.47|141.101.98.47]] 14:58, 12 March 2014 (UTC)

I later decided that 0y20140310.175959 would be a good way to extend it to specify both date and time, and it still parses as a single C token if that property is useful.

| − | We should be doing universal coding for the year. All dates start with a 1, followed by the number of zeroes equal to the number of digits in the number of digits in the date. Take 2015, it has 4 digits, 4 has 1 digit, so it starts with "10" then append the number of digits in the date, "4" and finally the date "2015" to get "1042015". In 8000 years this would be "10510015" in 1e10 years it would be "100101000002015". A computer drops the one, checks the number of leading zeroes, reads in that many digits, then reads in that result in digits to read in the year. With the leading 1 it can still be stored as a binary number rather than a string, and needs no starting or ending indicators, and will expand indefinately to store any date ever to exist. --[[Special:Contributions/188.114.106.41|188.114.106.41]] 21:22, 20 May 2015 (UTC)

| − | I know this is a few years late, but it probably should be noted that Before Christ (or Before Common Era for those of you that get hung up on that sort of thing), years were expressed by the establishment of rulers (Year of Rameses, Year of Xerxes, etc.), so in old times you actually did have repeating years.
