What's a strange logic: why get Begin - End ? should be end - begin right? Your output in PCR above is NEGATIVE (09:30 - 18:30).
It mean there are some another parts in Time Schema to update the time wage type 1024. Please using standard program to extract Time Schema to find it. I forget program name already 
Or check Time Schema log step by step.
Btw you can add function Print ZT into your schema immediately after the PCR above, so u can see what's exactly value hold in Time Wage Type 1024. Good luck
