Reply to comment by [deleted] in eli5 Are GMT and UTC timezones somehow different? If so, how? by CrispyDairy

There can be as much as a second difference between GMT and UTC times, which is why we’ve been adding leap seconds ever few years to UTC. Starting in 2035, it’s been determined that we will stop adding leap seconds to UTC, so at that point UTC and GMT times will start to drift more, but still likely only by a few seconds. I don’t believe it’s been determined what we’ll do when the gap becomes greater.

I did not know that. I am glad that they are going away. Leap seconds are annoying to deal with.

It’s a very recent development. The vote or whatever was a couple weeks ago.

The gap may never become wider. Last year it was determined that a leap second should be deducted from UTC for the first time, but there was no precedent on how to do so. This was the driving factor for the removal of Leap Seconds overall.
