My system all of a sudden is now displaying time in military. And worst it goes up to ten days so on my analog phones I'll get a time of 79:00. I've tried to power cycle the system but and then the time shows fine but then again the hours go above 24 hours again! Has anyone have a similiar problem? Is this an indicator that the processor card is going out? I looked for an internal battery but don't see one.

Some processors had a pair of button-cell batteries, while others used a pair of capacitors.

Check to make sure that what you're seeing isn't the elapsed time counter as opposed to the time of day clock.

I don't think that the Merlin Magix has any effect on the date & time shown on analog phones....(but don't quote me on that).
