Wrong date & time in template

[Lukas Bruzdewicz]

I have a playlist with a scene where a template with the realtime date and time is showing. Since a few days, whenever I turn on ym TV the date and time is correct for a few minutes and then skips to 25th of novemeber 2025. 
I don´t know where this mistake comes from. Anyone with similiar problems and a solution please? Our customers are not happy about showing wrong time and date.
