D10 date defaults to 2000-01-01

Hi folks, my D10 records all parameters nicely, except for the date and time - 2000-01-01, with a time of 0000. It has done this since install around 2 years ago.
All other data shows up and charts well on Savvy Analysis (both in free mode and now in Pro mode).
How can I get the data logs to records date and time accurately please?
rgds, ife

Do you have a GPS connected? That's where many D10A installations get their time from.
Failing that I think it's a matter of either connecting the keep alive line to a permanent supply, or using an internal backup battery.

See page 3-3 if the D10A installation manual:
Pin 2 : Keep Alive Power.
A very low current power input which is only
used if both Master and External Backup Power
are not applied. Keep Alive draws just enough
current to keep the clock running. It draws less
than 1 milliamp of current when not charging the
internal backup battery.
Dynon Avionics recommends not connecting the
Keep Alive wire when the EFIS-D10A has an
internal battery installed or is connected to a GPS.
Keep Alive is only used in installations with no
battery or GPS to keep the clock running when
the unit is powered off.

As Robski says, you'll need a GPS connection to have reliable date information. Note that we no longer recommend the use of keep-alive, especially if youu have the EFIS backup battery installed.

Thanks to both - yes I do have a GPS connection for fuel range information, which I receive en route.
Is it the case then that I need a 'back-up' battery?
