Hi. Welcome to Fishingreminder.
If I am understanding your question correctly, no. The tide will be as per the tide station. But tide stations will (should) list offsets for their local area. The largest I have every seen is 3 hours.
Mark is the expert in this field. It might be possible to add a feature to allow manual input for time offsets. I will ask him about it next time we chat.
Cheers
