Chrome v67 timezones are broken! Why?

Question

After Chrome version 67.0.3366.0 the old date timezones are broken.

You can try it with:
new Date(Date.parse("1/5/1880 GMT")).toString();

You can try it on other browsers and see the correct results.

For example, if you are in Central Europe, for 2018 it will display GMT+0100 (which is correct) but for 1880 GMT+0053 (which is wrong). In case of Dubai it will become GMT+0400 and GMT+0341 in the same order.

Please explain it in details and not only put some links in the comments.

Answer 1

I speculate that it has something to do with Standard Time not having been adopted worldwide in 1880. According to Wikipedia it had been proposed by then, but acceptance came slowly over the next 50 years or so. Google might be computing Solar Local Time that far back. Just throwing the idea out there - I haven't checked the numbers.

Hi Aaron Sarkissian I saw this on stackoverflow https://stackoverflow.com/questions/50609860/browsers-time-zones-chrome-67-error and interesting. Maybe you saw it too.

Answer 4

it seems that after chrome 67 timezone is some how rounding of the time like in India it shows GMT+0521 old time and new time it shows GMT+0530 so the new update somehow taking the IANA timezone rather than os time zone or it just rounding of the time to its Ceil value

Jan Markus I don't think it is possible to travel back in time, even if you do travel into past the world line has to change even if you make no difference in the events, because the reality is that you didn't go there....

Answer 14

is it incorrectly adjusting for leap days, leap minutes or leap seconds? 2000 was not a leap year because every 400 years we have to skip 1 since the every 4 year pattern over compensates for the imprecision in a 365 day year compared to the actual hours, minutes , and seconds required to orbit the sun.
