When using a dynamic variable like the date {{now}} even with the proper time zone (LA, etc).. when someone says today or tomorrow it is not consistent. It is like the agent is not dynamic and instead hallucinates. I provided examples of what to do and it still gives wrong answer every now and then. Anyway to fix this? Has someone else experienced this? Is this something that you just accepted to your production and are okay with it being wrong once in a while?
