Mysql - showing Long timestamps and readable Dates

A while ago I had to find a certain date in the database, but the date column was defined as LONG.
I discovered you can easily turn a LONG to a date, using the following syntax :

select startTime, FROM_UNIXTIME(startTime / 1000) , UNIX_TIMESTAMP() from LiveSessionDetails limit 1;

NOTE that you have to divide the LONG value by a 1000 otherwise you get a blank value.
