Probavbly using the Universal Coordinated Time. Check System Value below. If it shows 00:00 then you are using reenwich time. Here on east coast of US we are at -05:00

And note that you can’t change QUTCOFFSET directly in any recent release of the OS. The system will change QUTCOFFSET after you set QTIMZON correctly. And before attempting to change QTIMZON directly, you should first try the WRKTIMZON command. Study it and learn what it does.
Of course, you haven’t yet told us anything about your system; so it’s mostly guesswork. It’d be nice to have at least a hint about what your OS version/release is.
Thanks for help our OS is V5R4M0.
