Clock zeroed, no intervention

[Jeykey]

Happened to anybody ? Got to the bike and the clock just changed, noticed the time wasn´t correct at all. Gel battery is about 2,5 years old, no fault indication, didn´t do any maintenance job, didn´t even touch the bike.

That normally happens when you push the starter & the battery is low. Often a sign the battery is dying in my experience.

Could be worth a quick check of the multiplugs in the headlight too. You'd get the same effect if the ones to the clocks are loose & the perm 12v feed gets interrupted by a bad connection. There must be a fuse for it too, but I couldn't tell you which one but shouldn't be hard to tell as there's not many of them.

Mine did this several times while I was setting up the TPS & cold start, started to get a bit concerned until it clicked that I had been disconnecting the battery to reset the ECU values

This may sound odd, but what was the time indicating?  If it was 12.00 or 1.00 the change in time has just happened, as in when you go to start it, if it's just way off, means whatever happened was hours ago.

Definitely signs of a failing battery. A way to check is to hook up your multimeter and see what voltage you have with ignition off, then ignition on and then as you push the starter.

Ignition off = 12.5v (resting)
Ignition on = 12.1 maybe 11.5v
Engine start = anything above 10.5v is good, less than  that is bad.
Engine running = 14.3-14.5 v if generator is working correctly.

Yeah, just losing power somewhere, clock default is 1, same on every digital clock. Batt test first, as described above.

Thanks lads for all the useful replies. I´ll definitely check the battery, even have a dedicated batt tester. I discarded the batt fault cause it´s not that old and I normally take care of ´em. More than a week parked I´ll connect a ctek charger,... Will also check plugs.
