So just to point out as i did on some IETF list also that the IANA TZ even introduced a mechanism to support sub-second precision. All this is solely political, and it is nothing but politeness and also (a bit, or two) desire to integrate in the western (-originated) technology (domination (colonialism)) that keeps timezones in this scheme. But if China for example would change to _real_ Shangai time instead of the mutilated western-compatible variant, then suddenly ~1.4 billion people would be off, and for example the email standard could not cope with it because the Date: header does not have second resolution for timezones, and it seems the IETF is currently cementing this fact in a revision of RFC 3339 if i got that right. This is, imho western biased focus, sheer ignorance, or maybe only what PHK has in his email footer for decades. Does not matter in that run down aggressive dishonest western lead world of pseudo moral with much more to be said but all off-topic, but would be an indication of mutual respect and politeness. |I guess a bigger issue with existing software, if for some reason it |couldn't be updated anymore, would be the maximum offset that can be |accepted or represented.
