The 34 hour restart provision will still be in effect. However, drivers will only be allowed 1 restart per week (168 hours). Up to 2 hours either side of a sleeper-berth period while in the passenger seat will count as off-duty. Drivers inside a parked CMV who are not in the sleeper berth must log it as on-duty.
Daylight saving time ( DST ), also referred to as daylight saving (s), daylight savings time, daylight time (United States and Canada), or summer time ( United Kingdom, European Union, and others), is the practice of advancing clocks to make better use of the longer daylight available during summer, so that darkness falls at a later clock time.
Coordinated Universal Time or UTC is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and ...
Circadian clock. A circadian clock, or circadian oscillator, also known as one’s internal alarm clock is a biochemical oscillator that cycles with a stable phase and is synchronized with solar time . Such a clock's in vivo period is necessarily almost exactly 24 hours (the earth's current solar day ).
The modern 24-hour clock is the convention of timekeeping in which the day runs from midnight to midnight and is divided into 24 hours. This is indicated by the hours (and minutes) passed since midnight, from 00 (:00) to 23 (:59), with 24 (:00) as an option to indicate the end of the day.

One décime is equal to 10 decimal minutes, which is nearly equal to a quarter-hour (15 minutes) in standard time. Thus, "five hours two décimes" equals 5.2 decimal hours, roughly 12:30 p.m. in standard time. [8] [9] One hundredth of a decimal second was a decimal tierce.
The Sun appears to move in the sky over a 24-hour period while the hour hand of a 12-hour clock face takes twelve hours to complete one rotation. In the northern hemisphere, if the watch is rotated so that the hour hand points toward the Sun, the point halfway between the hour hand and 12 o'clock will indicate south.
The 12-hour clock has been developed since the second millennium BC and reached its modern form in the 16th century. The 12-hour time convention is common in several English-speaking nations and former British colonies, as well as a few other countries. There is no widely accepted convention for how midday and midnight should be represented: in ...
