The iPhone Daylight Savings Time Glitch
In 2010 a glitch in the iPhone software meant that thousands of iPhone users in New Zealand and Australia were early for work when their phone failed to automatically adjust itself for the Southern Hemisphere going into Summer time. Not too much of an issue, users of iPhone’s just did an extra hour or took a longer lunch.
However, this glitch manifested itself a few weeks later when (in the Northern Hemisphere) daylight savings time (DST) ended and the clocks went back one hour. In the UK thousands of users reported that their phones had not automatically adjusted themselves and were subsequently an hour for work. For those who weren’t aware of the issue in the UK then experienced the same problem only a couple of weeks later.
Then in 2011 another glitch with the iOS software meant that for some users the clock again didn’t change at all and for some even went the wrong way! This issue continued to manifest itself until the phones clock was manually reset by its user.
The good news is that in 2012 people using iOS 5 or above eradicated the issue, but you need to make sure that you have the [flag text_color="#ffffff" bg_color="#003366"]time zone setting turned on[/flag] otherwise your iPhone may still not adjust.
How do I turn the time zone setting on?
To make sure that your iPhone adjust’s itself for DST you need to enable the time zone setting on the iPhone. To do this follow these instructions:
Go to [flag text_color="#ffffff" bg_color="#003366"]Settings[/flag] > [flag text_color="#ffffff" bg_color="#003366"]Privacy[/flag] > [flag text_color="#ffffff" bg_color="#003366"]Location Services[/flag] > [flag text_color="#ffffff" bg_color="#003366"]System Services[/flag] > and make sure [flag text_color="#ffffff" bg_color="#003366"]Setting Time Zone[/flag] is [flag text_color="#ffffff" bg_color="#01cb21"]turned on[/flag]
Some disable the setting to try and improve battery life. If when you check, it is disabled, then be sure to reboot your device once it has been enabled. You also need to ensure that your device is using iOS 5 or later and that it is not in airplane mode to ensure that it works.
Will it change if you are abroad?
The simple answer is [flag text_color="#ffffff" bg_color="#01cb21"]Yes[/flag]. This is why the setting is under the location settings menu, so the phone can detect where you are and adjust for DST accordingly.
If you still don’t trust your iPhone to get yourself up on time then we suggest you invest an alarm clock which you have been sure to manually set before going to bed, either when the clocks go back or the clocks go forward.
