How to convert Unix epoch time in SQLite

Could you help me convert UNIX epoch time into format yyyy-mm-dd hh:mm:ss (24h) in SQLite? (GMT+7 would be appreciated).

Example: from 1319017136629 to Wednesday, October 19, 2011 4:38:56 PM GMT+7.

p/s: Just looked around and found a solution:

SELECT datetime(1319017136629, 'unixepoch', 'localtime');

But i am still looking for a way to batch convert UNIX epoch time in SQLite.

Same as stated above:

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

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.

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

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