I strongly support the positions of Stephen and Jon. I recall we had a big precision discussion several years ago, and the arguments against changing the precision made then are just as applicable today. Howard On Jul 29, 2022, at 3:26 AM, Jon Skeet via tz <tz@iana.org> wrote:

I second this. From the perspective of Noda Time (the project I maintain) we decided long ago that the precision of UTC offsets would be one second.
Basically this change will mean extra work for me to truncate back to seconds. (I'm pretty sure we're using the vanguard data - I'd need to double check.)
Obviously the small inconvenience for one developer shouldn't be regarded as a veto, but I wanted to mention it as one data point. There are definitely costs to this - are there also known concrete benefits, in terms of consumers wanting to use this data?
