Hello siddino;
Here is how the TOD datatype is defined in Step & (from the online help):

TIME_OF_ DAY (Time)

Size in bits:32
Format options:Time in steps of 1ms
Limits:TOD#0:0:0.0 to TOD#23:59:59.999

So basically you if you view the TOD variable as a DINT you should see a number between 0 and 86400000 (number of ms in 24 hours).
I think you should be able to apply a GE_D or LT_D comparator instruction for DINTs in your program to compare two values.
Hope this helps,
Daniel Chartier
