Remember to set your clocks forward tonight

The transition from June to July will be delayed by circumstances beyond everyone's control. Time will stand still for one second on Saturday evening (June 30) because a "leap second" will be added to let a lagging Earth catch up to super-accurate clocks.

....

As a result of this difference, atomic clocks, which are used to set all other clocks, can get out of sync with the Earth and periodically have to be adjusted. A leap second has to be added from time to time to make up the difference.

The next time will be Saturday, when the master clock at the United States Naval Observatory will be adjusted at 7:59:60 p.m. Eastern Daylight Time, or 23:59:60 Coordinated Universal Time (UTC). This will put Mother Earth about four-tenths of a second ahead of the clock, giving her a bit of a head start as we transition into the new month of July.
