'GMT Bug' in iOS 8 Calendar Syncing Causing Time Zone Confusion for Users

by

A growing number of users on Apple's support forums are reporting an issue with iOS 8 and the time zones of synced calendar events, reports Forbes. Known by users as the "GMT bug," the issue is causing confusion as calendar events sometimes see a secondary time zone (frequently GMT) added on.

The issue is documented in a lengthy thread on Apple's support forums that was started shortly after iOS 8 was released, and it has continued to gain significant attention since that time. According to user reports, calendar events created in one time zone are converted to another timezone possibly when they sync across a server.

Most of the affected appointments originate from either Google or Microsoft Exchange calendars that are linked to the default iOS calendar app. While the appointment remains at the correct time for the user, the actual time setting becomes defined in GMT rather than the user's local time zone, which can cause issues if the user edits the entry without realizing the different time zone.


There are conflicting reports, however, over whether this behavior is indeed a bug or not. Apple support representatives reportedly have confirmed to at least one user that the company is aware of the issue and working on a fix, while others have been told this is expected behavior.

The issue may in fact be related to a "Time Zone Override" setting in iOS 8 that allows users to maintain a consistent time zone for their calendars even while traveling to different time zones, but even if the GMT addition is intended behavior the implementation is clearly causing confusion for many users.

Apple last updated iOS to version 8.1.2 in December with a fix for disappearing ringtones. A minor iOS 8.1.3 update is in testing with Apple engineers and retail staff, with a public launch expected soon. Developers are now also using iOS 8.2 betas, the fourth of which was released in last week. None of the public or beta versions of iOS are yet confirmed to contain a provision to address this issue.

How long has time been around again? Time bugs just make me laugh. It's funny how something so old is still gotten wrong by so many [programmers].


As a programmer, I can tell you that time zones cause some of the biggest headaches across all types of development. It's really not that surprising.

This is nothing compared to the bug (it's actually a feature but I refuse to call it that) in OS X's calendar which changes the TIME of ALL events (in the past, present and future) if you simply move your computer into a different country. I mean holy hell, you just VISIT Paris and suddenly your flight is 5 hours earlier than it should be just because you didn't specify that at the time when you will be looking at the screen, you will be in the GMT+01 time zone.

And no turning on Time Zone Support doesn't solve this.

Paper calendars are still far more reliable than ones made by Apple.

Calendars should not know about the existence of time zones at all. It's a calendar, not a world clock. A meeting at 5pm is a meeting at 5pm, period. I don't care where it is, surely I know what the current time is in the current location I happen to be in.

UTC wtf is dat?

Oh yea it's jealously ... GMT the time zone they don't want to use because it's a British invention.

(So the story goes)

(All this drama because)

UTC and GMT are not the same. Although the time difference between both is almost zero (approximately due to leap seconds and earth rotation not being constant), GMT is a time zone while UTC is not (it is an atomic scale).

Whenever you do anything with times or dates in computing you should always use UTC and ISO8601 (https://en.wikipedia.org/wiki/ISO_8601) Years/Months/Weeks/Days internally. Depending on someone's location or time zone you then convert from UTC to what's relevant wherever they are at that particular time.

Seems like this would be a great time for the new Google Calendar for iOS app to come out.
