In Postgres, a time zone represents a region of the earth with a uniform standard time. Time zones allow us to convert local time to UTC(Coordinated Universal Time) or vice versa. Time with time zone is stored i
In Postgres, the functions likeNOW(),CURRENT_TIMESTAMP,TRANSACTION_TIMESTAMP(), etc., retrieve the current date and time with time zone information. However, if we use them for the TIMESTAMP column, then the timezone information will be skipped, and the date time values will be inserted in...
is a timestamp with time zone. PostgreSQL never examines the content of a literal string before determining its type, and therefore will treat both of the above as timestamp without time zone. To ensure that a literal is treated as timestamp with time zone, give it the correct explicit typ...
