Is there a way of seeing what your take off time was whilst in flight (if you don't have a route planned).  I guess you can see it on the PLOG if you have a route however most of my flying is taking people up for experience flights and so I rarely have a route in but I do need to know how long I've been airborne and am frequently forgetting my take off time!

Have you tried planning a simple "within an area" local route? That will give you access to the PLOG and other instruments will then be helpful as they'll relate to your takeoff/landing airfield.

I do normally use the "fly within 25nm" option however this doesn't generate a plog as far as I can tell this no take off time visible.

You can switch to the PLOG during flight by tapping the position report at the top of the screen. If you actually have a flight being logged, you should see an extra section at the top detailing your takeoff time and how long you've been flying, etc.

Great thanks Tim.  I thought I had tried that but will give it a go next time I'm up. Many thanks.
