I am part of a realm and we have been having some major issues recently it is becoming common that people get disconnected from the realm and then when they rejoin they have been reset back to a time in the past this is extremely annoying and NEEDS to be fixed.

Thank you for your report!
However, this issue is Invalid for the bug tracker.
When all players are disconnect that usually means that the realm server crashed. Crashes such as these are logged automatically by the game or realm server and investigated further by the development team internally, so they are not generally kept on the bug tracker.
If you can provide a list of steps that someone else can follow to consistently reproduce a crash then feel free to create a new report. Please be sure to always search for duplicates before creating any new report. Please see the Bug Tracker Guidelines for more information.
Sometimes when a crash occurs the world will revert to a previous saved state. This specific issue is tracked as MCPE-12347.
