:From the revision history, the only things that look like they could be interpreted as being censored are the "JEWISH SHILL" thing from the (no longer present) "incomplete" tag, which is hate speech, and the "SOON THE TRUTH WILL BE REVEALED" thing that briefly replaced all of the actual content, which is vandalism.

The "share" functionality on mobile systems may serve as a rather catch-all protocol. On PC not many apps have this in mind.

Is this really all that common? Am I the only one who came to explainxkcd because I only half got the joke? Sure, a photo of a screen with data is useless and stupid, but why make a comic about it?

Entymology? Misspelled "entomology" or (more confusingly) "etymology"?
Psychology lower risk than micology? Absolutely hogwash!
:The comic has been updated, so it was just a typo. [[Special:Contributions/141.101.99.35|141.101.99.35]] 16:05, 18 October 2017 (UTC)

Molasses storage is misplaced -- should be in the quadrant to its right. See [https://en.wikipedia.org/wiki/Great_Molasses_Flood]. 21 dead and 150 injured. [[Special:Contributions/108.162.219.52|108.162.219.52]] 14:12, 18 October 2017 (UTC)
Agreed that it did get out and kill people. But only once in something like 200 years and only a few. (Is this where the phrase slower than molasses in January comes from?)
I would not expect that this would be a common danger.

Ah, but there was another [https://en.wikipedia.org/wiki/Honolulu_molasses_spill|spill in 2013 in Honolulu]. (I just learned of it from the "See Also" section of the Wikipedia page on the Great Molasses Flood.) That one didn't kill any people (though it was an ecological disaster) but it speaks to risk. Anyway, the item ''is'' in the right quadrant. Arguably is should be further to the right, but also arguably not, since conducting experiments in the area could lead to more accidents.[[User:Jqavins|Jqavins]] ([[User talk:Jqavins|talk]]) 16:08, 18 October 2017 (UTC)

I think entymology is a reference to [https://xkcd.com/1012 1012]
[[Special:Contributions/162.158.91.95|162.158.91.95]] 14:50, 18 October 2017 (UTC)

I think the title text may have a somewhat humorous naming scheme derived from the Great Molasses Flood Wikipedia discussion page: https://en.wikipedia.org/wiki/Talk:Great_Molasses_Flood
There's a lengthy discussion about changing the name from "Boston Molasses Disaster" to "Great Molasses Flood". I noticed that Randall used both approaches to describing the events in the title text, but maybe that was a coincidence.

I am not impressed. Movie supervillains often use paleontology (dinosaurs), geology (volcano/earthquake) and astronomy (comets). Also, there is a tendency to pair marine biology with laser-optics. And, to actually dominate the world, a real-life villain will probably need to use cunning linguistics at some level or the other. --[[User:Nialpxe|Nialpxe]], 2017.

Apparently there are some mistakes in the Roman numerals in the comic, the year MMXII is 2012. Also LVII/CCLXV = 57/265, whereas February 27th is the 58th day of the year (which has 365 days). --[[User:Ulm|ulm]] ([[User talk:Ulm|talk]]) 07:55, 27 February 2013 (UTC)

1179: ISO 8601

2013-02-27T15:28:36Z

Jqavins: /* Explanation */ Added to the roman numeral fraction explanation for 2012 leap year

{{comic
| number = 1179
| date = February 27, 2013
| title = ISO 8601
| image = iso_8601.png
| titletext = ISO 8601 was published on 06/05/88 and most recently amended on 12/01/04.
}}

==Explanation==
{{w|Public service announcement}}: The two most commonly used date formats in the world are {{w|Date format by country|dd.mm.yyyy and mm/dd/yyyy}} (the symbols separating the values, as well as the year being 2 or 4 digits notwithstanding). These differences are often causes for debate. However, the comic explains that the {{w|International Organization for Standardization}} (ISO) has standardized dates in the yyyy-mm-dd format, in its {{w|ISO 8601}} standard.

The comic then lists many formats as "discouraged". This list starts with commonly used formats, which include the two above as well as other commonly used ones, such as dd/mm/yy. However the list then starts listing formats ranging from uncommon to absurd, such as writing the date partly in Roman numerals and painting the date in m/d/yy format with white paint onto a hissing black cat.

The title text mentions two dates in either the dd/mm/yy format or the mm/dd/yy format, but because the day values in both dates are less than 13, the format used is ambiguous. In yet another date format, the standard was published on 5 June 1988 and amended on 1 December 2004.

The other mentioned formats are:

{| class=wikitable
! Date !! Explanation
|-
| 02/27/2013
| MM/DD/YYYY, used mostly in the US
|-
| 02/27/13
| MM/DD/YY
|-
| 27/02/2013
| DD/MM/YYYY, used e.g. in South America, Canada and Europe

|-
| MMXII-II-XXVII
| Year-month-day in Roman numerals, but for '''2012'''-02-27
|-
| MMXII [and] LVII [over] CCCLXV
| Year and 57/365. This representation marks the start of the day, which is 57 days after the year started. Probably should have been 2013 instead of 2012; if 2012 were intended, this should have been MMXI[and]LVII[over]CCCLXV'''I''', as 2012 was a leap year.

| {{w|Unix time|UNIX Timestamp}}, but for '''2012'''-02-27

| Year/month/day with the parts written as arithmetic expressions
|-
| 27 [''over''] 02 [''over''] 2013
| An obfuscated date format not used ordinarily. This can be considered a compromise between the different formats: Since we cannot agree on which position in the date the day, month and year parts shall be, we just write them all in the same place. We don't even need separators, which we cannot agree on either.
