gpsmap 923: wrong tide time at Guernsey

Hi,

Being at Guernsey (UTC+1), the Tide information is wrong.

For instance, today (August 10th 2023), the device shows low tide at about 08h00 localtime , whereas the actual low tide is

at 06:59 localtime.

The time is set to automatic time zone, and the device time is indeed the right local time.

I cannot figure out why there is that 1 hour offset, that rather sounds like a bug.

Thanks
