MySQL - Matlab and stupid time stamp which includes the tenths of a second.

Hello, I'm working on a program that takes some data from a database in MySQL.

I want to extract some measurements that have been stored with a really stupid time stamp like this:

Reference
266023     which corresponds to time stamp      2012-09-04 17:27:07.344 
........
........
19388000  which corresponds to time stamp      2012-10-04 17:27:07.766

The code I use to extract data is using the Reference number as condition:

curs = exec(conn, ['SELECT * FROM `data` WHERE Reference >= ''266023'' AND Reference <= ''19388000'' ']);

For me it is easier to search using the time stamp.

My problem is the stupid format of the time stamp. It counts also the tenths of a second.

Is there any way to exclude the tenths of a second in the search conditions?? Note:the time stamp is char 1x23. How can I put in condition only the 1x19 (exclude he .xxx)

Could I write something like this??

curs = exec(conn, ['SELECT * FROM `data` WHERE Time >= ''2012-09-04 17:27:07'' AND Time <= ''2012-10-04 17:27:07'' ']);

Thanks
