Solar noon varies from 11:53 in November to 12:23 in February where I live (it keeps closer to the hour during DST [1]); an adjustment of 37 seconds doesn't seem to be very big compared to the 30 minute swing we observe over the year. It seems more reasonable to wait until the gap gets large enough to coordinate an hour jump in clocks with enough advance notice that there's a good chance of having it happen simultaneously. At the rate of leap seconds in the last 60 years, that should be several thousand years away; hopefully none of my software is running then.

[1] I'll save the rant on DST.
