When I was testing out a small compact house on my realms server, I slept in a bed (I was in survival and the only one on) and I woke up like normal, but the time did't change. I tested it in creative and it didn't work.
-Note: It is caused by daylight cycle daylight cycle
I have a realm and I sleep perfectly fine and time changes. Did you make /gamerule doDaylightCycle false. If so, the time isn't supposed to change.
