Date

Date

A simple date type. Dates are stored as milliseconds since the epoch. They are immutable, and all functions that modify dates return a new date. Used with Duration values.

Dates can be useful for modeling values that change over time. Below is a simple example of a function that returns a normal distribution that changes over time, based on the number of years passed since 2020.
