Using 12am as an end time with 12 hour time format shows wrong end time

The formatting of the 24hr end time is in OfficeHoursDateHelper~format().
The second parameter indicates that a time is an end time.
The error should be from line 176 (// Format the 24-hr end time from 0 to 24:00/2400 using a trick.)

The change should only be done for 24 hour formatting, not 12hr formatting. Not sure why/how this is introduced.

I see this was already reported in 🐛 Midnight displaying as 11:00 pm when using 12 hour display formatter Fixed . Let's discuss over there.
