To get the unix timestamp using JavaScript you need to use the getTime() function of the build in Date object. The database schema already exists and can't be changed. This function converts the date to the specified date format and returns the number of seconds between the specified date and Unix epoch. Investigate this query with EXPLAIN before use in production because it may be slow on big tables: WITH orders AS ( SELECT email , first_value(dt_cr) OVER wnd1 AS min_date , nth_value(dt_cr, 2) OVER wnd1 AS second_date FROM orders WINDOW wnd1. However, some differences can cause issues if not tested properly. Continuing our series of PostgreSQL Data Types today we're going to introduce date and time based processing functions.

I read the Postgres documentation and was still confused, so I played with some queries and finally figured it out. It's a best practice to use the GetMetricData API instead of GetMetricStatistics, because you can retrieve data faster at scale with GetMetricData. I will use the shorter type names for simplicity. The time zone notion in particular is mainly a political tool these days, and it makes no sense on an engineering principle: there's no. We're leveraging shell expansion to create three directories, a top level postgres-express-react-node-tutorial directory containing bin and server. There are many formats.
