Problem with the day/night cycle

Hello everyone

I have a problem that I do not explain. During the day, on my server, the time jumps directly at midnight without explanation.

I can go to bed, to spend the night. Once a few hours, the time switch to midnight

What mods and plugins do you have?

Hi,

And does this happen without Sponge installed?

I asked myself the question

I tried to disable all .jar sponge / plugins and the server does not start anymore
