Month View Next Month & Year Bug
-
Under certain circumstances the Month View next month link shows shows the current month instead of the next month. Clicking on that next month link does actually displays the current month’s calendar and then the next month link actually shows next month. At the same time, clicking on the next year link jumps forward only 11 months and shows the previous month for the next year.
The circumstance under which this occurs is when UTC is the next day relative to local time.
The cause of this bug is the assignment statement in app/view/calendar/view/month.php that begins on line 184. Specifically, the problem is line 185, which is “->set_timezone(‘UTC’)”.
What happens is that the time zone is set to UTC and the value of $orig_date is set to the first day of the month. But locally it’s still the previous day so instead of $orig_date being June 1, 2016 it is May 31, 2016. The the assignment on line 203 increments the month and sets the date to 1 so $orig_date now has June 1, 2016. The problem is that next month is actually July.
The same thing happens for the next year link except that instead of incrementing the month the year is incremented. The result is that the next year link will show May 2017 instead of June 2017.
I tested by removing line 185 and the problem went away.
