I’m not sure I would agree with that. ISO-8601 is ambiguous, and very difficult to parse. For example, here are a couple valid ISO-8601 strings. Could you let me know what they mean?
P1DT1H
R10/2021-208/P1Y
T22.3+0800
22,3
2021-W30-2
2021-W30-2T22+08
P1Y
20
Taken from here. My favorite is the last one (20). If someone just wrote 20 and told you to parse it using ISO-8601, what would you get? Hour? It could even be century (ie. 2023%100)!!
So I would argue that ISO-8601 is just a wee bit too flexible. Personally, I like RFC 3339 just a bit more…
Edit: that said, I would definitely agree that something along the lines of 2021-07-27T14:20:32Z is better than any regularly accepted alternative, and I pretty much format my dates that way all the time.
This is a bit of an outdated view in my opinion. If you’re a KMT voter (ie. 60+), then sure, this is a common view. Younger generations (DPP voters) however don’t really view themselves as Chinese. I think this view will die out eventually.
Of course, for the most part, this is all off the official record because of the implications. Chinese nationalists will argue that this is wrong because it’s still written in the Taiwanese constitution or whatever, but the truth is that regular people in Taiwan couldn’t give less of a shit about China. De facto, most Taiwanese consider themselves their own country with no legitimate claims to China.
