Hey @ESMP, thanks for jumping into the community 
No such function for today() currently exists within Baserow. As it turns out, the it’s more complex than what initially meets the eye. There’s a lot more to it, but in a nutshell, it has to do with connecting to other formulas in the database and updating all of the values almost in real-time.
You can imagine the sort of lift this would be for databases with hundreds of thousands or millions of records. 
It’s definitely something we’ve looked into internally though, and hope to have it in the future.
