Tosca > {DATE} or {DATE[][][]} function

For some reason I ALWAYS forget what the correct syntax is with this function. So hereby a post to forever remember:

First: a good search term in the Tosca documentation:
DATE AND TIME EXPRESSIONS

Syntax:
{<EXPRESSION>[<Basedate>][<Offset>][<Format>]}

In normal human readable:
{DATE[basedate][offset][format]}

Key-letters for specifying the format:

d	days
M	months
y	years
h	hours
m	minutes
s	seconds
