Scheduled task not running (whhhyyyyy)

OS: Windows Server 2012 R2
Java Version: 11.0.6
Tomcat Version: Apache Tomcat/9.0.31
Lucee Version: Lucee 5.3.8.3-SNAPSHOT

Hey,

I’m busy with a scheduled task, but it not firing and I’m totally lost right now.
So I see this task in de web admin environment. This task has an interval
“once” and it should fire after a two minutes making the task.

When I dump the task on the website then I see it’s valid and all the data looks
correct. Even more weird: when I check “execute” through the web admin then
it all works like it should. It’s just not being fired while the time and date is correct.
Als if I look at the server time. I see no errors in the log.

What is happening, please help me.
Thanks!

UPDATE: it actually does the task, but 10/20 min later than the given time. And if I look
in de web admin then I see the correct system time, very weird.
