If you try to publish an event and put 1pm as the start time, it lets you publish the event but sets the data and time to January 1, 1970 without a start time. Same issue for end time.
I know that a 24 hour clock time format is required, however not all authors of the site know this.
So, i’m asking that you impliment a warning function as well as a label to instruct authors that they must use a 24 hour clock format for the time. If they try to add 1pm or 1:00 or anything other that 13:00 format, show a red error message and dont allow them to publish the event.
