Hi,
I'm seeing that product/brand on ebay and amazon, so you can reach out to sellers of the item on those websites and they should have the accessories that you need.
Thank you.
I guess that the Time Zone you entered is for B.S.T. and the programme automatically compensates for Daylight saving time (i.e. one hour back) during our winter. Try setting time to B.S.T. and it will jump back to D.S.T. which is correct until the end of the month if you are in the u.k.
