In the MRBS calendar, adding a PM event requires using military time(24 hour clock) even though there are AM and PM radio buttons. If I enter 1 in the start time hour box, click PM, and save the reservation goes in a 1AM time slot. Since we do not see the hours the library is closed at night on the calendar, it looks like the reservation has disappeared. The only way to locate the AM reservation is to go to the month view for that room. When I go to edit a PM reservation the start time appears normal (1 in the box and PM button checked) but if I do not change the 1 to 13 before saving the updated entry, it moves the reservation to 1 AM.
