PHP格式（'H：m'）增加了一分钟

Question

In my database, there's a field with "00:00:00" and a field with "15:00:00".

When I echo this in my php page with format('H:m') they show like "00:01" and "15:01". Without that format, they show like "00:00:00" and "15:00:00".

Does anyone know what could possibly cause this?

Answer 1

m isn't minute, it is month. i is minute.
