Difference between iMac and iPad for Darksky Forecast

I have HassIO running on a Raspberry Pi and I’m currently at version 0.90
My main interface is from an iMac using Chrome but I also sometimes use an iPad using the Home Assistant App. Intention is to use the iPad as a wall mount interface.
Most so far is OK but I have noticed that my forecast from Darksky is slightly different on my iPad compared to my iMac.
Basically the forecast time is 7 hours ahead on my iPad compared to my iMac (iMac time is correct).
I have attached to screenshoots - one from each to illustrate.

Any idea why there is a difference?
Also - if I on the iPad uses Safari and log into the same IP address as on the iMac I still get the wrong time.
