How do you make a "days since 2000" equivalent in snap?

Could you guys help me?

I'm from scratch, and i'm trying to replicate the "days since 2000" block.
I need the block because I am currently porting a scratch project into a snap project, and it includes that block.
I think it's math, but i can't think of how to do it.

Please help :smiling_face_with_tear:

If you find the timestamp for 00:00 Jan 1 2000 and then subtract the value of the current time in milliseconds reporter and then divide that by number of milliseconds in a day then you should get the same number (or maybe you have to use 00:00 Jan 2001 - I don 't know what the Scratch reporter gives)

This works for me (i think).

Thank you!
