I recently got an Apple iPhone 4, a hand-me-down from a good friend of mine who upgraded to an iPhone 5. One of the first things I noticed is this strange bug in the weather app that comes with the iOS 6.

The weather app shows the weather condition of a specified location. In default mode, it displays the day of the week, a little icon conveying the weather condition (sunny, cloudy, rainy, etc.) and the day's high and lows.

One can slide down on the current day, and it will slide open and display the hourly weather conditions for the day, as shown in the following two screen-shots:



As you can see these screen-shots have been taken at 6 PM (18:00), so the expanded view for Saturday, shows the temperature starting at 18:00, then 19:00 (7 PM) and moving forward to 23:00 (11 PM) after which, the day changes to Sunday, and it continues to display the temperatures for 0:00 (midnight), 1:00, 2:00 and so on. All this is as expected and good!

However, after midnight (0:04), when the day switches, in this case from Saturday to Sunday, the app display this strange behavior (a software bug!). Instead of continuing to show Sunday 0:00, 1:00, ... it displays the listing under the Saturday heading:



Note that the date at the bottom of the weather report is in fact correct, as it changed from "1/26/13" (i.e., Jan. 26th 2013 which was a Saturday) to "1/27/13" (i.e., Jan. 27th 2013, the Sunday).
