How to Convert Unix Timestamp to Local Date In Oracle?

2 minutes read

To convert a Unix timestamp to a local date in Oracle, you can use the TO_DATE function along with the TIMESTAMP data type. First, you need to convert the Unix timestamp to a TIMESTAMP data type using the TO_TIMESTAMP function. This will give you a timestamp value that represents the Unix timestamp in Oracle. Then, you can use the TO_DATE function to convert this timestamp to a local date format based on your desired format mask.


For example, you can use the following SQL query to convert a Unix timestamp value stored in a column named 'unix_timestamp' to a local date format:


SELECT TO_DATE(TO_TIMESTAMP(unix_timestamp, 'YYYY-MM-DD HH24:MI:SS.FF'), 'YYYY-MM-DD HH24:MI:SS') AS local_date FROM your_table_name;


This query will convert the Unix timestamp stored in the 'unix_timestamp' column to a local date format based on the format mask 'YYYY-MM-DD HH24:MI:SS'. You can modify the format mask based on your requirements to display the date in a different format.


What is the function to convert unix timestamp to local date in Oracle?

The function to convert a Unix timestamp to a local date in Oracle is as follows:

1
2

SELECT TO_CHAR(TO_DATE('1970-01-01', 'YYYY-MM-DD') + (YOUR_UNIX_TIMESTAMP / 86400), 'YYYY-MM-DD HH24:MI:SS') AS local_date
FROM dual;


Replace YOUR_UNIX_TIMESTAMP with the actual Unix timestamp you want to convert. This query will return the local date and time in the format 'YYYY-MM-DD HH24:MI:SS'.


What is the best practice for converting a unix timestamp to a local date in Oracle?

To convert a Unix timestamp to a local date in Oracle, you can use the following SQL query:

1
2

SELECT TO_CHAR(TO_DATE('1970-01-01', 'YYYY-MM-DD') + NUMTODSINTERVAL(<unix_timestamp>, 'SECOND'), 'YYYY-MM-DD HH24:MI:SS') AS local_date
FROM dual;


Replace <unix_timestamp> with the Unix timestamp you want to convert. This query adds the number of seconds specified in the Unix timestamp to the Unix epoch ('1970-01-01') and then formats the resulting date as a local date string.


What is the significance of the epoch time when converting a unix timestamp to a local date in Oracle?

The epoch time, also known as Unix time or POSIX time, represents the number of seconds that have elapsed since the Unix epoch (January 1, 1970, UTC). When converting a Unix timestamp to a local date in Oracle, the significance of the epoch time lies in the fact that it serves as a reference point for calculating and determining the exact date and time from a given timestamp value.


By using the epoch time as a starting point, Oracle can accurately calculate the local date and time from a Unix timestamp by adding the timestamp value to the epoch time and adjusting for any timezone offsets. This conversion process allows users to easily work with Unix timestamps in Oracle databases and accurately display date and time information in a local context.
