After Permanent DST: These Apps Still Show the Wrong Time — Force-Update Guide for Each One

Your phone clock updated correctly after the permanent daylight saving time change — but several apps are still showing times that are off by exactly one hour. This happens because apps store their own time zone logic separately from your device's system clock. Here's the force-update fix for each app that commonly gets stuck.

Why Apps Get Stuck After a DST Policy Change

When governments change DST permanently (ending the biannual clock change), it triggers a time zone rule update — not just a one-time clock adjustment. Apps that hardcode UTC offsets (like "EST = UTC-5") instead of using named zones (like "America/New_York") won't automatically adopt the new rule. They need to be manually refreshed or updated.

Quick diagnostic: If your phone clock shows the correct time but a specific app is off by exactly 1 hour, the app has a stale time zone rule. Work through the app-specific fixes below.

Google Calendar

Symptom: Events shifted by 1 hour, or new events defaulting to wrong time zone

1. Go to calendar.google.com → Settings (gear icon) → General → Time zone.
2. Even if it shows the correct city name, click the dropdown → select a different time zone → click Save → then go back and reselect your correct time zone → Save again. This forces Google to re-fetch the current UTC offset for your zone.
3. For events that already shifted: Google Calendar should auto-correct events linked to named zones. Events created with a fixed UTC offset won't auto-correct — edit those manually.
4. On mobile: tap your profile icon in the Google Calendar app → Settings → General → Time zone → reselect your zone.

Outlook (Desktop and Web)

Symptom: Meetings showing 1 hour early or late; "Time zone differs from calendar" warning appearing

1. In Outlook desktop: go to File → Options → Calendar → Time zones → Current time zone → change to a different zone → OK → reopen and change back to your correct zone → OK.
2. Check for pending Office updates: File → Office Account → Update Options → Update Now. Microsoft patches DST rule changes through cumulative Office updates — running an outdated version is the most common cause of persistent Outlook time zone issues.
3. In Outlook Web: go to Settings (gear icon) → General → Language and time → Time zone → reselect your zone → Save. Sign out and back in after saving.

Zoom

Symptom: Scheduled meetings showing wrong start time; calendar invites out of sync

1. Log into zoom.us on a browser (not the app) → click your profile picture → Settings → scroll to "Date and Time" → Time Zone → reselect your correct zone → Save Changes.
2. In the Zoom desktop app: go to Settings → General → confirm "Use computer's time zone" is checked. If it's unchecked, Zoom is using a manually set zone that may be outdated — uncheck and recheck to force it to pull from your system.
3. For meetings you've already scheduled: after updating your Zoom time zone, edit each affected meeting and resave it — this regenerates the calendar invite with the correct time. Send updated invites to participants.

Microsoft Teams

Symptom: Meeting times in Teams differ from Outlook calendar by 1 hour

1. Teams pulls its time zone from your Outlook/Microsoft 365 profile — fix Outlook first (see above), then Teams should sync automatically within a few minutes.
2. If Teams is still off after fixing Outlook: sign out of Teams → sign back in → the profile sync will pull the updated time zone from your Microsoft account.
3. On mobile Teams: tap your profile photo → Settings → the time zone is inherited from your device — confirm your phone's time zone is set correctly at Settings → General → Date & Time → Set Automatically → on.

Apple Calendar (iPhone and Mac)

Symptom: Events on iPhone showing different times than the Mac, or recurring events shifted

1. iPhone: Settings → Calendar → Time Zone Override — if this is enabled and set to a city that hasn't received the DST rule update yet, all events display in that city's old time. Disable Time Zone Override to use your current location's time.
2. Mac: System Settings → General → Date & Time → Time zone → turn off "Set time zone automatically" → wait 5 seconds → turn it back on. This forces a fresh time zone rule download from Apple's servers.
3. Update macOS: Apple distributes time zone rule updates as part of macOS point releases. Go to System Settings → General → Software Update and install any pending update.

Alexa and Google Home Routines

Symptom: Smart home automations firing at the wrong time after permanent DST

• Amazon Echo: Open the Alexa app → Devices → Echo & Alexa → [your device] → Device Settings → Device Time Zone → reselect your zone (even if it already shows correctly — the reselection forces a rules refresh). Then go to More → Routines and check each time-triggered routine — automations with specific times (e.g., "turn on at 7:00 AM") do not auto-adjust for policy changes, only for standard DST shifts.
• Google Nest/Home: Open Google Home app → tap your device → Settings → Device Information → Time Zone → reselect. Check Routines for time-based triggers and update manually.

Workforce Scheduling Apps (When I Work, Deputy, Homebase)

Symptom: Shifts appearing 1 hour off for some employees

• If the shift times are wrong only for you: go to your profile in the app → Account Settings → Time Zone → reselect your correct zone.
• If shifts are wrong for the whole team: this is an admin-side setting — contact your manager or the app's admin. The organization's base time zone needs to be updated in the admin panel.
• For When I Work specifically: Account → Profile → Time Zone → update → Save.

Bottom Line

Apps that won't update after permanent DST almost always need the same two-step fix: update the app itself (to pull the latest time zone database from the developer), and then manually reselect your time zone inside the app's settings (even if it looks correct — the reselection forces a rules refresh). For calendar apps showing shifted events, fix Outlook or Google Calendar at the account level first — Teams, Zoom, and other integrated tools will inherit the corrected time zone from your primary calendar account. Smart home routines with hard-coded times (e.g., "7:00 AM") never auto-adjust for policy-level DST changes — those require manual edits every time a permanent time rule changes.
