SQLite "now" is not actually a fuction, but "now" is a timestring parameter that is used in various SQLite functions to fetch the current date and time.

Syntax:

There are three types of syntax for now function in SQLite:

snippet

strftime(format, 'now')
i.e. 
strftime('%Y-%m-%d','now')
strftime('%Y-%m-%d %H-%M','now')
strftime('%Y-%m-%d %H-%M-%S','now')
