Unique Identifier - Using dates & times

Thank you very much @Kal_Lam for this post. But, I don’t know why but for a month this formula not has been working.

There is a new formula which calculate it:

concat(substr(now(), 2, 4), substr(now(), 5, 7), substr(now(), 8, 10), substr(now(), 11, 13), substr(now(), 14, 16), substr(now(), 17, 19))

Curiously is the same formula but the values are in the opposite position.

Could you check why this is happening?

Best regards,

Thank you for sharing this with the entire community, @segadu78! It should be very helpful!
