12/29/2023 0 Comments Postgresql timestamp![]() Here's more about the EXTRACT() function. If you'd like to calculate the difference between the timestamps in seconds in PostgreSQL, subtract one date from the other (here: arrival - departure) then extract EPOCH from the difference to get it in seconds. ![]() Solution 3 (difference in seconds):ĮXTRACT(EPOCH FROM (arrival - departure)) AS difference In this solution, the resulting column is also of the type interval. Eve::PgSqlType::Timestamp is a PostgreSQL timestamp without time zone type adapter class. Here, it would be AGE(arrival, departure). I’ll use, hereinafter, the short spellings (plain) timestamp and timestamptz, respectively, for theseand timestamptz to denote either one of these. If you'd like to get the difference in years, months, days, hours, minutes, and seconds, use the AGE(end, start) function. The relevant data types here are time, date, and timestampwhere the latter has a without time zone and a with time zone variant. Solution 2 (difference in years, months, days, hours, minutes, and seconds): Return Value The PostgreSQL TOTIMESTAMP () function returns a timestamp with time zone. To construct format strings, you use the following template patterns for formatting date and time values. 2) format The format for timestamp argument. The difference will be of the type interval, which means you'll see it in days, hours, minutes, and seconds. Dates and timestamps (with or without time zone) are all comparable, while times (with or without time zone) and intervals can only be compared to other. 1) timestamp The timestamp is a string that represents a timestamp value in the format specified by format. To calculate the difference between the timestamps in PostgreSQL, simply subtract the start timestamp from the end timestamp. data type TIMESTAMP just have one param is timezone and its use server timezone setting. Solution 1 (difference in days, hours, minutes, and seconds): You'd like to calculate the difference between the arrival and the departure. In the travel table, there are three columns: id, departure, and arrival. You have two columns of the type timestamp and you want to calculate the difference between them.
