ok I found three ways to convert correctly the milliseconds unix time to human readable time format

mysql> select from_unixtime(floor(1517874876754/1000));
+------------------------------------------+
| from_unixtime(floor(1517874876754/1000)) |
+------------------------------------------+
| 2018-02-05 18:54:36                      |

1 row in set (0.00 sec)

$ awk '{print strftime("%c", ( 1517874876754 + 500 ) / 1000 )}'

$ date -d @$(  echo "(1517874876754+ 500) / 1000" | bc)
