Time is Different in Canada
Some other carriers were affected but more sporadically, with the problem being traced back to Bell substituting a -5 in front of Greenwich Mean Time, rather than a -4, which told phones that it was six days later and had them reset to that incorrect time. Some folks found that company managements were not particularly sympathetic to their lateness, given they were unaware of the problem, while others did not consider any excuse a viable one for being an hour late. It is possible to turn off the automatic date and time updating on an iPhone, and it will still correct for DST as that is embedded in iOS, but the phone will no longer update if you cross a time zone. The alternative is to get an old alarm clock, as they did not update automatically and avoid any battery complications by plugging it in. We live in a complex world.
