here is the simple source code to split DATE_AND_TIME to Year,Month,Day,Hour,Minute,Second.

Sorry, but I can't find how to attach source file (wow) . That is why I paste it.

You can easy convert to DINT seconds value by multiply Hour by 3600, Minute by 60 ... and finaly sum it.
I am not sure what exactly you want to do, but this example is a good start.

Hope you can understand the following
source code:

The provided sample is for DATE_AND_TIME datatype, TOD is an IEC datatype which is the elapsed time since 0:00 midnight and is stored in milliseconds.
So just copy the TOD to a DINT variable and you will have the elapsed time in ms.
