How is the time column actually declared? If it's got limited precision
(eg, time(0)) then I would expect a current_time value just before
midnight to be rounded to 24:00:00, eg, 23:59:59.765321 -> 24:00:00.
That's not a bug IMHO.
You would probably be better off to replace this design with a single
timestamp column.
