Thank you for the quick fix (Re-add quarters in time) it is appreciated. I can at least now continue entering events into my site.
Suggestion
I really think that the quick pick should be for the date only and have a text field for the hour and another for the minutes. Entering the date manually can be tricky (that is why the date picker is a good thing), however time is easier to enter manually rather than scrolling through a long list of hours and minutes.
Something like this:
Start: [hh]:[mm] (_)pm
End: [hh]:[mm] (_)pm
If they don’t enter any time in the start or end time fields, then just don’t display that time field in the listings or display –:– if you must display something. Of course you will employ a filter to remove any invalid entries (ex: >23h or >59m)
Note: Not everyone understands the 24 hour clock. If they enter an hour greater than 12, automatically convert to 12 hour clock and select the ‘pm’. Of course behind the scenes and in the database you will likely continue to calculate, store and export the time in 24 hour format, however for entering and display using the 12 hour clock is preferred by most.
