How to convert Unix epoch time in SQLite


sql sqlite unix epoch

To change the values in the database, use the UPDATE command:

UPDATE MyTable SET MyColumn = datetime(MyColumn, 'unixepoch', 'localtime')

sql sqlite unix epoch

1319017136629 is a value in milliseconds, which is not UNIX epoch time;therefore it has to be divided by 1000 and rounded to integer seconds; only then DATE() and DATETIME() will convert.

SELECT DATETIME(ROUND(dateColumn / 1000), 'unixepoch') AS isodate FROM tableName

Converting database values to localtime is unfortunate; conversion on output is less problematic.

The Y2038 problem might already be worth a consideration.

sql sqlite unix epoch

SELECT DATE(ROUND(1601272453000 / 1000), 'unixepoch')
