Daylight Savings Time Bug hits iPhone

iOS 4.1 DST Bug
iOS 4.1 DST Bug

A bug ate my Apple. Fortunately the said bug did not hit me as hard as it did others, because in Poland 1st of November is a holiday. It was still a monday, so my iPhone tried to wake me up, as it was told to. Almost. I was really surprised to see that the time is one hour PAST the usual time of alarm. I am running most recent version of iOS 4.1 (8B117) on iPhone 3G. I have tested it a few times and found out the following:

  • Alarms with no repeating will sound properly at the right time
  • Alarms with everyday repeating will sound at the right time as well
  • Alarms set to repeat on selected days will sound at a different time

Additionally, after quick research on Google I found, that:

  • In Europe the alarm will sound one hour past the set time
  • In US, NZ and Australia it will sound one hour earlier than set
  • iOS 3.1.3 remains unaffected
