erl Posted October 30, 2010 Share #1 Posted October 30, 2010 Advertisement (gone after registration) My M9 has recently returned from Solm's for a rebuild at which time it also had the latest firmware installed. I have only just noticed that now the clock is running seriously slow. It loses several hours each day. Originally, with the earlier firmware, it was fine. Has anyone experienced this and is there an easy correction? Don't really want to re-send to Solm's for another 2-3 months 'holiday' fix. Is it possible that re-installing firmware 1.138 may fix it?

AlanJW Posted October 30, 2010 Share #2 Posted October 30, 2010 Maybe the internal battery? Reloading the latest firmware can't hurt, however. Link to post Share on other sites More sharing options...
marknorton Posted October 30, 2010 Share #3 Posted October 30, 2010 Trying doing a full reset from the menu after reloading the firmware and then reset the date and time options, possibly changing the display format and other options back and forth. These configuration options are stored in NVRAM and if the layout of the information is changed for a new firmware release, the firmware may not interpret the information from the real time clock correctly. Don't know how it is on the M9 but on the M8, a Ricoh chip was used for the RTC. These chips can be adjusted for exact timekeeping by writing calibration data to them as part of the camera set up. Depending on what was done to your camera, it's possible this calibration was messed up. I'd try the reload/reset first and hope...

erl Posted October 30, 2010 Author Share #4 Posted October 30, 2010 Thanks Mark. I have done as you suggested and will now see if the clock holds time over a reasonable period. Link to post Share on other sites More sharing options...
ho_co Posted November 4, 2010 Share #5 Posted November 4, 2010 Erl-- Just curious. Did resetting fix the problem? Link to post Share on other sites More sharing options...
erl Posted November 5, 2010 Author Share #6 Posted November 5, 2010 Yes, well good enough! It seems to have lost about 1 minute over about 5 days. I don't think I will be sending it back for that. However, my 21 year old SAAB Aero has a dashboard clock that NEVER needs re-setting except for daylight saving. Thanks Mark, your suggestion seems to be the go. As part of the re-setting, I did reverse the calendar from dd/mm/yyyy to yyyy.mm/dd. Quit happy with that as is. Link to post Share on other sites More sharing options...
marknorton Posted November 5, 2010 Share #7 Posted November 5, 2010 Advertisement (gone after registration) That's good news, next time the camera goes in for service, you can ask them to trim the clock. I am of course assuming Leica built in that capability and do not just rely on the accuracy of the crystal. Link to post Share on other sites More sharing options...
ho_co Posted November 5, 2010 Share #8 Posted November 5, 2010 Erl-- When I was a kid, we had a car with a "self-adjusting" clock. Whenever you reset it, it adjusted its timekeeping; so, the theory was, after a few adjustments it would have adjusted itself flawlessly. Of course, there were no instructions about whether the clock would expect these few adjustments to take place on a daily basis, a weekly basis, or some other. We finally decided that a gain or loss of about five minutes a day was as close as we were going to get. And the "self-adjusting" clock wasn't in the following year's car.

Double Negative Posted November 10, 2010 Share #9 Posted November 10, 2010 Maybe for the M10, Leica can spring a little extra for a Swiss quartz movement. Link to post Share on other sites More sharing options...
