Date/Time Strings

Leap seconds, like 31/12/16 23:59:60 (also another non-US date format).

@ColorXJH This is not an appropriate type of conversation for this thread. In fact, attempting personal conversations and asking to move to QQ is so off-topic for a GitHub Issues thread that many projects will ban you.

I suggest you explore the world of programming-related IRC channels instead. (And be sure to read any rules listed or linked in each channel's topic line.)

I think I've seen "0/0/1900" used as a null date, and Google says that "1/0/1900" is how Excel displays 0 as a date.

[joedragons]

Does this make #55 obsolete? Or at least the answer to it "yes?"=)

[designgrill]

Not every divisible by 4 year is a leap year. 2100 will not be and 1900 wasn't. It might help to include corresponding dates.

Also:

• Dates that are valid in DD/MM/YYYY format but invalid in MM/DD/YYYY format, to catch any naive programmers who assumed that the rest of the world functions just like the US. E.g., 25/12/2000.
• Dates that catch people who thought the Julian calendar system was still in effect. E.g., 1900-02-29.

And if you want to get ESPECIALLY tricky:

• Dates that really WERE valid in one specific country, but would be totally invalid normally. E.g., 1712-02-30. See http://nodatime.org/1.3.x/userguide/trivia and https://www.timeanddate.com/date/february-30.html for more details.
