This article explains how (and when) to use "today/now" date expressions. It also gives you an example knowledge map to explore "today/now" date expressions inside the Rainbird Studio.

In Rainbird, concepts can be ‘date’ concepts. Date concepts should be used when a date will be either input into or output by Rainbird. Rainbird can use date expressions to transform and calculate dates. Date expressions can be combined with other date, transformative and comparative expressions to ‘retrieve’, ‘add’, ‘subtract’ or ‘compare’ time. This section will focus on two date expressions, today() and now():

today(): Rainbird is able to generate today’s date at midnight as a value (e.g. if it’s the 2nd of February 2021, Rainbird would generate 2021-02-02 00:00:00) and use the value in expressions.

now(): Rainbird is able to generate the date and time the query is run at as a value(e.g. if it’s the 2nd of February 2021 12PM, Rainbird would generate 2021-02-02 12:00:00) and use the value in expressions.
