US and Canada time zone map
The United States and Canada run on 12 different clock settings, from Newfoundland time (UTC-3:30) to Hawaii (UTC-10), and 14 states plus several provinces are split between two zones. The map shows each zone with a live clock, the 2026 changes in Canada and the time a driver’s log uses.

Rule applied: the record of duty status uses the time standard in effect at the driver’s home terminal (49 CFR 395.8(f)(8) in the US; section 80 of SOR/2005-313 in Canada).
2026 changes: B.C. (UTC-7 after March 8), Alberta and the Northwest Territories (UTC-6) and Manitoba and Ontario west of 90° W (UTC-5) did not turn clocks back on November 1, 2026. Saskatchewan’s Time Act, 2026 aligned Lloydminster with the rest of the province. These clocks follow those rules even if your device has not been updated.
Checked November 5, 2026. Time laws change: check again before you rely on a time near a zone line.

Why time zones matter in trucking
Hours of service are counted in the time of the driver’s home terminal, not the clock at the shipper. A driver based in Toronto who delivers in Winnipeg logs Toronto time for the whole trip. Knowing which zone a stop is in, and whether it still changes its clocks, keeps appointment times, log entries and dispatch messages in step.
Every stop, recorded with its time
High Point GPS fleet tracking records every trip with its stops, the distance run and idle time, so dispatch sees when a truck really reached a customer. Geofences around yards and customer sites record arrivals and departures, and IFTA distance is recorded by jurisdiction.
Get a quoteTips for working across time zones
Set the ELD to the home terminal’s time zone and leave it there: the log should not change when the driver crosses a zone line.
Write appointment times with the zone, such as 8:00 ET, so nobody arrives an hour early or late.
Several Canadian provinces stopped changing their clocks in 2026. Check that phones, tablets and dispatch software have the update.
In a split state, check the county of the stop. Indiana, Kentucky, Tennessee and Florida each have two zones.
Time zone questions
- What time zone does an ELD log use?
- In the United States, 49 CFR 395.8 requires the record of duty status to use the time standard in effect at the driver’s home terminal. In Canada, section 80 of the Commercial Vehicle Drivers Hours of Service Regulations says the same: local time at the home terminal. The log does not follow the clock where the truck is.
- How many time zones are there in the US and Canada?
- US law sets nine standard zones: Atlantic, Eastern, Central, Mountain, Pacific, Alaska, Hawaii-Aleutian, Samoa and Chamorro, the last two for territories. Canada adds Newfoundland time. Since 2026, several provinces keep one offset all year, so Alberta now shares Saskatchewan’s time and British Columbia shares Yukon’s, which adds clock settings.
- Which provinces stopped changing their clocks in 2026?
- British Columbia moved to permanent Pacific time (UTC-7) after March 8, 2026. Alberta, the Northwest Territories, Manitoba and Ontario west of 90° W did not turn their clocks back on November 1, 2026. Saskatchewan and Yukon already kept one time all year. Quebec, the rest of Ontario and the Atlantic provinces still change.
- Does Arizona observe daylight saving time?
- No. Arizona stays on Mountain standard time, UTC-7, all year, according to NIST. The Navajo Nation in northeast Arizona is the exception and does observe daylight saving time. Hawaii also stays on standard time all year. In summer, most of Arizona shows the same time as California, and in winter the same time as Colorado.
- Which US states have two time zones?
- Under 49 CFR part 71, the split states are Alaska, Florida, Idaho, Indiana, Kansas, Kentucky, Michigan, Nebraska, Nevada, North Dakota, Oregon, South Dakota, Tennessee and Texas. In most of them the second zone covers a few counties, such as El Paso in Texas or four Upper Peninsula counties in Michigan.
