Try FROM_UNIXTIME(unix_timestamp,format)
e.g. 1194873780 = 12th Nov 2007 @ 08:23am, then
FROM_UNIXTIME( 1194873780, '%d %m %Y');
would yield 12 11 2007, You can format it the way you want, for more details about date formatting check DATE_FORMAT(date,format) function in MySQL.

ndb_delete_all
NDB_DELETE_ALL(1) MySQL Database System NDB_DELETE_ALL(1)
NAME
ndb_delete_all - delete all rows from an NDB table
SYNOPSIS
ndb_delete_all options
DESCRIPTION
ndb_delete_all deletes all rows from the given NDB table. In some cases, this can be much faster than DELETE or even TRUNCATE TABLE.
Usage
ndb_delete_all -c connect_string tbl_name -d db_name
This deletes all rows from the table named tbl_name in the database named db_name. It is exactly equivalent to executing TRUNCATE
db_name.tbl_name in MySQL.
The following table includes options that are specific to ndb_delete_all. Additional descriptions follow the table. For options common to
most MySQL Cluster programs (including ndb_delete_all), see Options Common to MySQL Cluster Programs(1).
Table 17.16. ndb_delete_all Options and Variables: MySQL Cluster NDB 7.2

| | Perform the delete in a single | |
| --transactional, | transaction (may run out of | All MySQL 5.5 based releases |
| | operations) | |
| -t | | |
+--------------------------+-----------------------------------+-------------------------------------+
| | Run tup scan | |
| --tupscan | | All MySQL 5.5 based releases |
+--------------------------+-----------------------------------+-------------------------------------+
| | Run disk scan | |
| --diskscan | | All MySQL 5.5 based releases |
+--------------------------+-----------------------------------+-------------------------------------+
o --transactional, -t
Use of this option causes the delete operation to be performed as a single transaction.
Warning
With very large tables, using this option may cause the number of operations available to the cluster to be exceeded.
