Is it possible to update the date format for a C7 using Hub Variables? Having created what I thought was the Date format variable and saved it I cannot see it even though it states it is present.

The issues is across all dashboard for example here I can see the date and time of the last movement on a Candio smart sensor (Zigbee PIR Motion Sensor - Candeo) which shows US, Date format to us in the Mother Country this is the 10th of August.

Would be great to fix this please
