Pass the Unix timestamp as an argument to the TO_TIMESTAMP() function, as a result, the TO_TIMESTAMP() function will convert the given Unix timestamp to an equivalent date-time value. In PostgreSQL, the TO_TIMESTAMP() function is used to convert a Unix or Posix Timestamp to a DateTime value. The output proves that the TO_TIMESTAMP() function converted the Unix timestamp to an equivalent time using the scope resolution operator. Similarly, a Unix Timestamp can be converted into an equivalent time by specifying the TIME data type with the Scope Resolution “::” Operator: SELECT TO_TIMESTAMP(1540295216.157677) :: TIME The TO_TIMESTAMP() function converted the Unix timestamp to an equivalent date using the scope resolution operator.Įxample 3: Converting UNIX Timestamp to Time For this purpose, the Scope Resolution “::” Operator must be used with the DATE data type, as shown in the following snippet: SELECT TO_TIMESTAMP(1540295216.157677) :: DATE Suppose the user wants to convert the UNIX timestamp to the equivalent date only. The TO_TIMESTAMP() function converts the input Unix timestamp to an equivalent date, time, and timezone.Įxample 2: Converting UNIX Timestamp to Date The TO_TIMESTAMP() function will convert the given Unix timestamp to the equivalent DateTime value: SELECT TO_TIMESTAMP(1540295216.157677) In the following snippet, a specific UNIX timestamp is passed to the TO_TIMESTAMP() function. Let’s comprehend this concept via practical examples.Įxample 1: Converting UNIX Timestamp to DateTime To achieve this, pass the Unix timestamp as an argument to the TO_TIMESTAMP() function, as a result, TO_TIMESTAMP will convert it into an equivalent timestamp.Ĭonsider the below-given snippet to understand the basic syntax of the TO_TIMESTAMP() function: TO_TIMESTAMP(unix_timestamp) In Postgres, the TO_TIMESTAMP() function is used to convert a Unix or Posix Timestamp to a DateTime value. This post illustrates a practical guide on converting the Unix TIMESTAMP to a date or Time value using the built-in TO_TIMESTAMP() function.Ĭonverting a Unix Timestamp to a DateTime in Postgres To tackle such a situation, the TO_TIMESTAMP() function is used in Postgres. While manipulating the dates and times, a database user may encounter a situation where he needs to convert a UNIX timestamp to a date or time value. The UNIX timestamp or POSIX time is formed as the system time of the Unix-based operating systems.
It is also known as the “ Unix Epoch”, “ POSIX”, or “ Unix” time. It represents the DateTime in seconds that elapsed since 00:00:00 UTC, January 1st, 1970. JavaScript does not support leap seconds.The “ UNIX TIMESTAMP” or “ POSIX time” is a widely used DateTime representation that is used in computing. Some browsers use the current DST (Daylight Saving Time) rules for all dates in history. Please note: All tools on this page are based on the date & time settings of your computer and use JavaScript to convert times.
