I found, that PIC24 RTC isn't of much use because of the rather high current consumption and complicated
handling of power supply for battery backup, so I decided to use a DS1337.

But I wouldn't be surprized, if PCD built-in RTC functions are not fully operational.
Did you observe particular problems?

No I haven't tried it. I was thinking of using it as an alternative to Dallas DS RTC parts. I thought with 4.100 on the horizon it might be working and I'd take the plunge and move to PCD and try it. Anyway if anyone has it working it would be nice to have some feedback.
