Who uses this article
Anyone who uses ServiceTitan on a PC or Mac in British Columbia, Alberta, the Northwest Territories, or Manitoba
Applies to
ServiceTitan in a web browser · Windows PCs and Macs
Permissions
You don't need a ServiceTitan permission to fix this. Many company PCs lock the time zone. If you can't change these settings, contact your information technology (IT) administrator.
What you're seeing
Times in ServiceTitan show one hour off on your screen. The times saved in ServiceTitan are correct.
ServiceTitan shows a warning in the header that your browser can't read your PC's time zone.
This can affect PCs in British Columbia, Alberta, the Northwest Territories, and Manitoba. These provinces stop changing their clocks on November 1, 2026.
Why this happens
There are two reasons.
Reason 1
Your Windows time zone doesn't know about the change.
On November 1, 2026, British Columbia, Alberta, the Northwest Territories, and Manitoba stop changing their clocks. Each province stays on its summer time all year. If your PC's time zone doesn't know this, ServiceTitan can show times an hour off.
Reason 2
Your PC uses one of Microsoft's new Canadian time zones.
Microsoft added the Windows time zones Pacific Time (British Columbia), Mountain Time (Alberta), and Manitoba. Browsers don't recognize these zones yet. The browser can't tell which time zone your PC uses, and ServiceTitan times show an hour off. This also causes the warning in the header.
Note: Use the zones in Check 1 until browsers support the new Microsoft zones.
How to fix it
Follow the check for your computer. Then confirm the fix and correct earlier bookings.
1Set your Windows time zone
Use this if you use a Windows PC. Pick the time zone that matches your province's clock all year. The city name in the setting doesn't matter.
Your province | Select this Windows time zone | Do not use |
|---|---|---|
British Columbia | (UTC-07:00) Yukon | Pacific Time (US & Canada), Pacific Time (British Columbia) |
Alberta and Northwest Territories | (UTC-06:00) Saskatchewan | Mountain Time (US & Canada), Mountain Time (Alberta) |
Manitoba | (UTC-05:00) Eastern Time (US & Canada), with Adjust for daylight saving time automatically turned off | Central Time (US & Canada), Manitoba |
Go to Settings › Time & language › Date & time.
Turn off Set time zone automatically.
In the Time zone list, select the zone from the table.
Manitoba only: Turn off Adjust for daylight saving time automatically.
Update Chrome to version 156 or newer. Go to ⋮ › Help › About Google Chrome, and click Relaunch if an update is available.
Close every browser window, and reopen ServiceTitan.
Note: Many company PCs lock the time zone. If you can't change these settings, contact your IT administrator.
✓ Done · After you reopen ServiceTitan, verify that the warning no longer shows.
2Set your Mac time zone
Use this if you use a Mac.
Go to System Settings › General › Date & Time.
Turn off Set time zone automatically.
Select the closest city: Vancouver, Edmonton, or Winnipeg.
Quit and reopen your browser.
✓ Done · After you reopen your browser, verify that the warning no longer shows.
