Daylight Savings, Mobile Phones and Calendars

Problem: Daylight savings is a wonderful thing, even if it does fade the curtains. What isn't so wonderful is how little companies care about it. Without fail whatever company I'm working at has issues with the transition to/from daylight savings. This year was no exception (solved after 3 Microsoft patches and a chicken dance). What wasn't solved was the time on my mobile phone (a Nokia 6110 Navigator in case you were curious... I call it my iNavigator and pretend I have a fancy iPhone). There were two distinct issues:
  1. Updating the mobile phone time
  2. Getting calendar entries from my Outlook calendar to display with the correct time on my mobile phone

Quick Solution: Under Time > Options > Settings make the following changes:
  • Network Operator Time: Change to Off
  • Time Zone: Change to the same as what your currently in e.g. Melbourne, Australia is currently (with daylight savings) in GMT +11. Might require setting your location to a totally different country (e.g. Solomon Islands - Honiara!)
  • Time: Now update to the correct time
Why it works / is required: Most smartphones have the daylight savings start/finish dates included as part of their firmware. So if a country/region changes these after your phone was built, and if they haven't released a firmware upgrade, then it will always think for instance Melbourne Australia is GMT +10 instead of GMT +11. Setting your timezone to a different country is fine because as far as I know, Outlook and your phone don't care what country your timezone is associated with, they only care what the associated GMT +/- value is. If you don't take off the Automatic Network Operator time, then of course it will update the timezone to be the current location which will be wrong. So follow the above steps until the phone recognises your area has started daylight savings.

Of course if you have a non-smartphone, it won't have GMT settings and so you shouldn't have any dramas. The only other high level information I found was here.

You've probably found this entry through Google. This blog is about things I haven't been able to find through Google (irony).

99% of questions I can find an answer for through everyone's favourite search engine, but it's the 1% that annoys me.

So this is a blog of random problems and solutions... hopefully it will help others having problems with that last 1%.
