Not only were frontend widgets showing UTC time,
the SQL query was also comparing UTC timestamp with local timestamps,
causing widgets to display shows in the wrong day, etc.
Another problem was that "On air today" widget was simply calling
GetNextShows which returns shows within next 48 hours.
Fixed by:
1. Under models/Show.php:
In the GetCurrentShow/GetNextShows/GetShowsByDayOfWeek functions,
added code to convert UTC timestamp to local timestamp or vice versa,
depending on which one is more suitable, in SQL queries, thus
removing inconsistency in timezones. Also, before returning query result,
added code to convert result to local timezone.
In GetNextShows, added an optional parameter endTime to limit the interval
of shows to get. This is useful for the "On air today" widget.
2. Under models/DateHelper.php:
Added a few timezone functions to help converting timezones easier in Show.php.
3. Under controller/ApiController.php:
Added todayInfoAction which is to be used by "On Air Today" widget.
Added StringLength validators for the UI fields. This way when user gave more than what
they should gave as the input, it's going to display an error msg.
The maximum length for the fields is queried from the database before the
fields were initialized.
