changing match times

[Potemy]

Let's say a match starts at 5am. But there's option to change to 23:00, 00:00, 01:11 etc... these timings are all on the same date?

They're on the same T11 day. For me, daily update is now 10am to about 11.30am during the winter season. For me, a T11 day would be from 11.30am to 10am the next day, so I can change a match from 11pm to 1am two hours later, which are different days for me, but still the same T11 day.
