Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist you today.
Sorry I didn't see your question earlier and to hear of any issue you are having with your clock radio.
If you still need help you with this issue:
Let me send you a link to the electronic (PDF) version of the "manual" for this unit.
Click here for manual --> https://docs.sony.com/release//ICFC414_US.pdf
Details for setting the time zone, clock, and date are in the second and third column of the second page.
You should see the manual appear or download when you click the link. If not, you will need to install a PDF Viewing program on your computer. I have another link to a no cost viewing program below - if you need it. Just be careful to UNCHECK any "optional offers" BEFORE using the "install now" button.
I hope this helps. Please let me know if you have any issues getting the manual or have any other questions about your clock radio.
If this has helped answer your question(s), please take a moment to rate MY service level (5-star is my goal) so that I get credit for my time helping you with this question.
You should see some "stars" (and SUBMIT button) to do that, but please let me know if you do NOT see them (you may have to REFRESH your screen) or can not use them.
Thanks, ***** *****
