It's now just past what computer people call "2018-01-01T00:00:00" (or, in more human-readable form, "2018-01-01 00:00:00 +00:00").
Some of you will remember that 2017 was exactly 1 day and 1 second shorter than 2016, owing to the leap second added a year ago at 2017-12-31T23:59:60.
Even thought 2017 was that much shorter than 2016, it seemed so much worse. But that's literally behind us now (or at least in the 13/24ths of the world on GMT or ahead of it). Here's looking to 2018 to be just a tiny bit better.
Happy new year!
