How long did my trip/drive take?

i would like to use the zone node from home-assistant-websocket
v2.1.4

i want to know the travel time between my zone(cottage) to my zone(home).
i would like do a few things with that date.
a) how long it took? output to a email or notification
b) would it be possible to put the date and how long it took in Home Assistant.
c) have Home Assistant show the drive has taken you 2:15 x times for each time it records.
can you think of anything else i can do with that data?

i tried and failed at using diff in the Function node

I figured out A in the middle of typing this.
