I have been using a system to keep track of time since 2021 but i noticed datetime can randomly start to slowdown and become unreliable.
I have noticed the datastore in my game getting filled up with inaccurate results because of this issue, this used to not happen back in 2021.
I do not know when this started happening, but i do know back in 2021 getservertimenow() was suffering from the same issue which I made a bug report about back then.
This issue with getservertimenow made me switch over to datetime.now back then because it was not suffering from the same issue and used it perfectly fine since then until this year when it started having the same issues.
I have a demo in the private message.
